Alanis Morissette

Alanis Morissette is not the person Rob Thomas thought she was.

Matchbox Twenty and its lead singer once saw her as a Zenlike soul, Morissette told Newsweek for its issue hitting newsstands today.

"He kept saying that whenever I wasn't with him, his imagining was that I was levitating somewhere, meditating," the Canadian singer said.

But then, "we had the most debaucherous, entertaining, hysterical time together, so they were the first to say that their perception of me was a little off," she told the magazine. She did not elaborate on the debaucherous details.
