Miss USA Tara Conner gets to keep her title if she checks into rehab. Here's a list of celebs who did rehab to avoid jail:

Mel Gibson

Mel Gibson ended his August 2006 fiasco pleading no contest to a charge of drunken driving under a deal in which he’ll serve three years’ probation, pay a fine and attend alcohol rehabilitation classes.

Boy George
In March 2006, Boy George agreed to enter drug rehab in order to avoid jail time on a cocaine charge.

Nick Nolte

Nick Nolte voluntarily entered a Connecticut clinic after his November 2002 arrest for suspicion of driving under the influence.

Rush Limbaugh

In April 2006, a judge ordered Rush Limbaugh to undergo at least 18 months of drug rehabilitation treatment. The agreement ended an investigation into allegations that Limbaugh illegally obtained prescription drugs.

Leif Garret

Leif Garrett was as shaky as a leaf when he appeared in a Los Angeles drug court Jan. 20, 2006, and agreed to enter rehab to avoid prison for heroin possession charges.

Tom Sizemore

Actor Tom Sizemore was ordered into drug treatment rather than prison after pleading guilty in October 2005 to possession of methamphetamine.

Courtney Love

Courtney Love may have been facing three criminal cases at one time, but the former Hole singer avoided the possibility of prison by cutting a deal and entering 18 months of court-ordered rehab instead.

Winona Ryder

A jury convicted Winona Ryder in November 2002 of grand theft and felony vandalism for a shoplifting spree in a Beverly Hills Saks Fifth Avenue. But when it came time to mete out a sentence, the judge took into account the prescription pain killers she had on her at the time of her arrest. As part of her sentence, which included community service and a $10,000 fine, the "Edward Scissorhands" actress was ordered to undergo drug and psychological counseling.

Nicole Richie

Richie was arrested for possession of heroin in 2003. Though she missed one court appearance to tape the first season of the reality show, Richie was sentenced to probation and ordered to complete a drug diversion program.

Charlie Sheen

Charlie Sheen was arrested in 1999 for driving under the influence. The charges forced him into rehab to avoid prison.

Kelsey Grammer

Kelsey Grammer of "Frasier" and "Cheers" fame flipped his Dodge Viper in 1987 while under the influence. He was put under house arrest, given probation and ordered to complete rehab.

David Crosby

In 1985, singer David Crosby was convicted of drugs and weapons charges in Texas and allowed to enter a drug rehab clinic instead of prison. But when he fled rehab, there was no second chance. The judge put Crosby behind bars, where the singer served a year.
