Pete: Ashlee's Not Expecting

Rumours claiming Ashlee Simpson is pregnant are being called a "witch hunt" by her fiancée.

In an email to MTV News, Fall Out Boy rocker Pete Wentz has fumed: "There is a witch hunt for people to be pregnant whenever they get engaged in Hollywood."

"This is all news to me. I can't wait for the story about how I'm really in a gay relationship and this is all just a cover... I mean really, this is crazy... I mean we're engaged, that's true, and happy about it."

Ashlee and Pete announced their engagement on April 9.
