Pete Wentz has denied that he and his fiancée Ashlee Simpson are not expecting a child. The Fall Out Boy rocker calls the rumors a “witch hunt.” “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,” he said in an e-mail to MTV.
