Just as Lindsay Lohan appears back on track - happy and healthy in a relationship with Samanta Ronson - a celebrity gossip tabloid is intent on bring the actress down.

According to Star, the formerly promiscuous skank is heading toward another drug and alcohol-driven breakdown.

"Lindsay's been drinking, doing cocaine and causing all-around mayhem for the past few months," an source told the magazine. "She quit going to Alcoholics Anonymous and has absolutely never taken recovery seriously. She's gotten progressively worse, and everyone in her life is really scared."

Lohan didn't take this affront lying down.

On her personal MySpace page, Lindsay called the allegations "ridiculous," adding: "According to [Star], I am one busy girl."
