Mary Weiland's "Fall to Pieces," a Memoir of Drugs and Rock 'n Roll

Love in the fast lane.

In her new autobiography, Fall to Pieces: A Memoir of Drugs, Rock 'n' Roll, and Mental Illness, Mary Forsberg Weiland, the wife of rockstar Scott Weiland, lays bare a life of drugs, sex and unbelievable excess.

A former model, Mary Weiland started her wild lifestyle at just 16 and would go on to marry one of the most notoriously drug-fueled singers of the '90s. The pair had a relationship virtually built on drugs, a fact she makes clear with a number of stories.

In one incident, at a party at Leonardo DiCaprio's house, the pair had to wear long sleeve shirts just to hide the trackmarks on their arms. Another time Mary decided to burn all of Scott's clothes after an argument. She would later be institutionalized with bipolar disorder.

"The bonfire was huge and very pretty. Everything went up in smoke quickly, except the shoe leather; the Guccis took the longest," she writes in the book. "The news reports said I'd torched $10,000 worth of Scott's clothes, which was wrong by a factor of eight. He was somewhat insulted at their estimate: 'Eighty thousand dollars, Mary,' he said later."

In another excerpt from the book, Mary writes about attending a party at the Playboy Mansion with Scott: "I had no clue till much later that Scott's time in the bathroom was spent with a crack pipe in his mouth."

The couple are currently split, and Mary is reportedly drug-free.
