Lindsay Dee Lohan was born in New York City on July 2, 1986, and raised on Long Island, N.Y.

Her parents, Michael and Dina, are former actors. She has three younger siblings: brother Michael, sister Aliana and youngest brother Dakota/Cody, all models. She is of Irish and Italian descent and was raised Catholic.

Her father had inherited his family’s pasta business and then sold it to become a futures trader. Her family was well-off, as her father moved on to be an investment banker and her mother became a Wall Street analyst.

Lohan started modeling for magazines and television commercials at age 3 with the famous agency Ford Models, doing work for Toys "R" Us, Calvin Klein and Abercrombie Kids. She also did a Jell-O commercial with Bill Cosby.

She then played central character Alli Fowler, daughter of Amanda Cory and Sam Fowler, on "Another World" in 1996 at age 10. But she left the show a year later for movies and at 11 played twins in the Disney remake of "The Parent Trap."

Her acting in both TV and the film was well-received by critics, and she was nominated for several young artist awards. She returned to school at Cold Spring Harbor, Long Island, and then Sanford Calhoun High School in Merrick, Long Island. She finished high school studies at home.

Lohan completed her initial Disney contract by making two TV movies, "Life-Size" in 2000 and "Get a Clue" in 2002.

She then played Jamie Lee Curtis’ daughter in the remake of "Freaky Friday" in 2003, which was her biggest monetary success in movies until "Mean Girls." Her brother Michael was an extra in "The Parent Trap," as were her other two siblings and her mother, who were also extras in "Freaky Friday."

Lohan won an MTV Movie Award for Best Breakthrough Female for "Freaky Friday" and another young artist award nomination. Lohan also sang a track on the "Freaky Friday" soundtrack called “Ultimate,” which paved the way for a budding music career.

In 2002, producer Emilio Estefan signed her to a five-album production deal. Two years later, she signed a recording contract with Tommy Mottola’s Casablanca Records.

In 2003 there were tabloid reports of a catfight with Hilary Duff over teen singer Aaron Carter, which both teens denied.

Lohan appeared on "That '70s Show" in 2004 with then-boyfriend Wilmer Valderrama, whom she moved in with at age 17.

The two made headlines as one of the few long-term young Hollywood couples until their breakup in November 2004, which got even more attention. Lohan was the subject of much speculation when she was briefly hospitalized for “exhaustion” following the breakup.

The media also pounced on Lohan’s appearance in paparazzi photos, alleging she’d had breast implants, which she denied.

Also in 2004, Lohan starred in "Confessions of a Teenage Drama Queen," which got a tepid reception at the box office. She also recorded more for this movie, completing four tracks on the film’s soundtrack.

Her breakout role came in 2004 with "Mean Girls," her first movie outside the Disney franchise, and the Lohan frenzy began as paparazzi began to follow her around and she partied it up with young Hollywood.

Through her affiliation with "Mean Girls" author Tina Fey, Lohan hosted "Saturday Night Live" three times in 2004, 2005 and 2006. Lohan also was chosen as one of People Magazine’s 50 Most Beautiful People in 2004.

That same year, Lohan was rooming with actress Raven Symone.

Lohan’s debut music album, "Speak," was released in December 2004, quickly went platinum and produced a gold single that she co-wrote, “Rumors.” She also recorded a track called "I Decide" for the soundtrack to "The Princess Diaries 2."

In December 2005 Lohan released a second album, "A Little More Personal (Raw)," which tanked on the music charts. A month later, it went gold anyway, and her single "Confessions of a Broken Heart (Daughter to Father)" turned the spotlight on her personal life.

The Lohans endured quite a rocky relationship: Her father did time for securities fraud and in 2005 went back to prison for aggravated unlicensed driving and attempted assault. Her parents went through nasty divorce proceedings, all covered by the media in detail as tabloids watched the effects on Lohan.

Also in 2005, Lohan got into a few car accidents, rear-ending another vehicle, being hit by paparazzi and hitting a van that had made an illegal U-turn. These accidents also made headlines, along with her rapid weight loss.

Lohan was hospitalized in 2005 and soon announced a new fitness and nutrition regimen.

In January 2006, Vanity Fair magazine attributed Lohan's rapid weight loss to bulimic episodes, although Lohan vehemently denied those reports. She also suffered an asthma attack that same month, which sent her to the hospital in Miami for two days.

Lohan did another Disney film in 2005, "Herbie: Fully Loaded," which featured her as an older character in her 20s, and Lohan hoped it would further her maturity with audiences. The film was a moderate success in the U.S. but did better internationally.

Lohan wrapped "Bobby," an independent film also starring Elijah Wood, in December 2005, and wrapped "Chapter 27" starring Jared Leto in March 2006.

Lohan's films "Just My Luck" (for which she reportedly was paid $7.5 million) and the more sophisticated "A Prairie Home Companion" (directed by Robert Altman) were released back to back in May and June 2006. She sang another soundtrack tune for the Altman film, a remake of "Frankie and Johnny."

In July 2006, Lohan was taken to the hospital after saying she was overheated and dehydrated while she was on the set of "Georgia Rule."

Soon after, producer James G. Robinson wrote a letter to Lohan saying, "We are well aware that your ongoing all-night heavy partying is the real reason for your so-called 'exhaustion.'"

He accused her of unprofessional behavior and of making up false excuses, and he threatened to take action against her to recover any "monetary damages."

Lohan's mom refuted the accusations, appearing on "Access Hollywood" and saying that Lohan had been working in 105-degree heat when she was taken to the hospital.

Dina Lohan said that Robinson's letter was out of line and not "a smart thing to do to a young girl."

In October 2006, Lohan told In Style magazine that she wants to get married and win an Oscar before she's 30.

In December 2006, Lohan revealed that she had been attending some Alcoholics Anonymous meetings.

She told People magazine then that she had been going to meetings for a year.

"I haven't had a drink in seven days. Or anything," she said to People. "I'm not even legal to, so why would I? I don't drink when I go to clubs. I drink with my friends at home, but there's no need to. I feel better not drinking. It's more fun. I have Red Bull."

Then, on Jan. 17, 2007, Lohan announced she was checking herself into rehab at the Wonderland Center in Los Angeles.

The New York Post's Page Six gossip column reported that the decision was spurred by an all-night drinking binge following the Golden Globes.

"I have made a proactive decision to take care of my personal health. I appreciate your well wishes and ask that you please respect my privacy at this time," the actress said in a statement.

Two weeks earlier, Lohan had been admitted to a hospital to have her appendix removed.

In May, Lohan and two others were in her 2005 Mercedes SL-65 when it crashed on Sunset Boulevard around 5:30 a.m., Sgt. Mike Foxen said. It appeared the actress was speeding, Lt. Mitch McCann said at a news conference.

Officers at the scene found a "usable amount" of a drug tentatively identified as cocaine, McCann said. He declined to say where the drug was found but did say Lohan was not carrying it.

Lohan was driven to a hospital for treatment for minor injuries, McCann said. The two others in her car were not hurt.

Officers received a 911 call about the accident and arrested Lohan at the hospital for investigation of misdemeanor driving under the influence of alcohol or drugs, McCann said.

She was released from custody because she was admitted to the hospital, police said.

Less than 48 hours after she was arrested, Lohan was partying with friends early on Memorial Day when she collapsed, according to photos and reports.

Later that day, Lohan "admitted herself to an intensive medical rehabilitation facility," according to a statement released by her publicist, Leslie Sloane Zelnick.

Lohan checked out of Promises Malibu Alcohol and Drug Rehab Treatment Facility on July 13, after a stay of more than six weeks. When she left, publicist Leslie Sloan Zelnik said Lohan would voluntarily wear an alcohol-monitoring bracelet.

Then, in the early hours of July 24, Santa Monica police received a call from the mother of Lohan's former personal assistant saying she was being chased by an SUV. Police arrived at the scene to find Lohan and the woman, whose daughter had quit several hours before, in a "heated debate" in the parking lot of Santa Monica's Civic Auditorium.

Lohan allegedly had been chasing the woman with two men. Police said she was unable to walk a straight line, touch her nose or follow a small light with her eyes, and officers also detected the smell of alcohol.

Lohan was booked for investigation of driving under the influence and driving on a suspended license, both misdemeanors. During a pre-booking search, police also found cocaine in one of Lohan's pants pockets, so she was also booked for possession of cocaine, authorities said.

Several hours later, Lohan was released on $25,000 bail.

After bailing her out, Lohan's attorney said the starlet had been tested daily in order to support her sobriety, and all reports had up until that point been accurate and timely.

"Unfortunately, late yesterday I was informed that Lindsay had relapsed," the attorney said. "The bracelet has now been removed. She is safe, out of custody and presently receiving medical care."

In August, Lohan reached a plea deal stemming from her two drunken-driving arrests that orders her to spend one day in jail and complete a drug program.

The 21-year-old actress avoided more serious felony drug charges because tests showed there wasn't enough cocaine on her to warrant them. Lohan will also serve 10 days of community service.

Lohan is reportedly a patient at the posh Cirque Lodge drug and alcohol rehab center in Sundance, Utah.

Lohan's latest film, "I Know Who Killed Me," opened in July to lackluster response.
