Lindsay Lohan in Cocaine Scandal

HOLLYWOOD - Actress Lindsay Lohan has returned to her wild ways, after she was filmed allegedly snorting cocaine--less than two months after leaving rehab.

The troubled star--who claims to have sobered up after her recent stint at the Los Angeles Wonderland Center--is also reported to have bragged to friends about her sexual exploits with actors Jude Law and Spider-Man star James Franco as she partied at trendy Hollywood nightclub Teddy's.

A friend tells British newspaper the News of the World: "That night I saw her do more than 20 big lines of cocaine. She was still up doing drugs at 11 a.m. She was blatantly doing it off tabletops, keys, books and in the wardrobe... In an average night Lindsay will do two and a half grams of coke on her own.

"She has told me that she has slept with James Blunt, Jude Law, Calum Best, Joaquin Phoenix, Benicio Del Toro, Jared Leto and James Franco."

And the source claims the Mean Girls star only checked into the Hollywood treatment center as a publicity stunt.

She adds, "Going to rehab was all for publicity. She wanted people to see her seeking help but it hasn't got her off the drugs at all."
