Robert Blake's slain wife was obsessed with celebrities and would frequently break the law to support her groupie lifestyle, friends say.

 LeebonnyBakley, 44, who was shot dead Saturday night near a California eatery, had a tainted track record that included stints in jail, fraud charges and various scams. 

Friends say all of her endeavors - including selling pornographic pictures of herself through the mail, running a sex chat line and phone-sex scams - allowed the starry-eyed New Jersey native to pursue her fanatical devotion to the famous. 

"She was a con artist, plain and simple, and a good one," said Frankie Jean Lewis, sister of legendary rocker Jerry Lee Lewis, one of Bakley's former lovers. 

Her dream of marrying a star finally came true last November when she married Blake after a DNA test revealed he was the father of her child. 

But Blake, a former child actor best known as TV's Baretta, wasn't the only star in Bakley's universe. The wannabe actress allegedly had love affairs with Lewis, Dean Martin, Frankie Valli and Christian Brando, among others, and even had a love child with Lewis. 

Bakley's celebrity odyssey began after she moved out of her parent's home in Morristown, N.J., and began pursuing a modeling and acting career in New York. She told her family she was studying with acting guru Lee Strasberg and that her two great ambitions in life were be a famous actress and marry a movie star. 

Instead, she married her first husband in New Jersey in the late '70s, and they had two children - now in their 20s. While he stayed home, she worked in real estate and was a groupie on the side. 

As her marriage came apart, she moved to Memphis to be near to her idol, Jerry Lee Lewis. 

To penetrate the living legend's inner circle, she befriended Frankie Jean Lewis and her sister Linda Gail Lewis. 

"She was just like the groupies in Almost Famous," Linda Gail recalled. "[Leebonny] loved the music and the men who made it. She was definitely obsessed." 

 FrankieJean Lewis said her hell-raising brother, who vomited when he heard about Bakley's slaying, first met the pretty blonde in the mid-1970s and continued seeing her even after she married Blake. 

Linda Gail said Bakley was always cagey about how she supported herself. Linda Gail said she was stunned - and horrified - when a London tabloid claimed in 1991 that she and Bakley were peddling porn to support themselves. 

Linda Gail won a libel suit against the Daily Mirror, and, ever the opportunist, Bakley asked for a share in the payout. But Linda Gail said the problem was the part of the story pertaining to Bakley was true. 

"[Leebonny] was a nice person, but she did some unusual things," said Linda Gail, who recorded an album with Van Morrison last year. "She also had an affair with my now ex-husband, who's an Elvis impersonator." 

Jerry Lee Lewis' wife, Carrie, detested the star-seeker who seduced her husband, Frankie Jean revealed. 

"Carrie hated her," Lewis said, adding that Carrie believed Bakley used Demerol to get near Jerry Lee Lewis, who has a long history of drug and alcohol problems. 

Jerry Lee Lewis and Bakley have an 11-year-old daughter. 

In 1989, Bakley was arrested for drug possession. At the time, she told cops she was holding them for a celebrity, but she wouldn't reveal who it was. 

After many years in Memphis and Arkansas, Bakley moved west and got herself introduced to legendary crooner Dean Martin. Shortly before he died, the Rat Pack partier introduced her to Marlon Brando's troubled son, Christian. 

In Christian, who was jailed for murdering his sister's lover in 1991, Bakley appeared to have finally met her soul mate. 

She became pregnant during their affair. 

"She was really hoping the baby was Christian's, but she made a mistake and slept with Blake, and it turned out it was his," Lewis explained. 

"Christian Brando wanted to marry her because he loved [Leebonny]. Blake didn't love her, and she felt trapped." 

 Bakleytrysted with Brando for two years, but after he discovered her betrayal, he was "devastated" and broke off the relationship. 

"It's . . . really bad, tragic," Brando told The Post yesterday of his ex-girlfriend's slaying. "I don't have any answers. It broke my heart. I couldn't believe it." 

 Brandosaid he hadn't spoken to Bakley in more than 18 months. 

"She was a nice lady," he said. "She was kind to me, and we used to have a lot of fun. 

"It's just a tragic thing, and I just feel bad. I don't feel that she had it coming like that." 

In the end, Linda Gail believed Bakley's life was sad and pathetic. 

"I don't think she had a lot of love in her," said Linda Gail. "[Leebonny] wasn't a sentimental person. 

"She didn't do drugs or drink much. Her addiction was celebrities. She was addicted to hanging around the famous."
