Ashlee Simpson's Fiance Says She's Not Pregnant

Ashlee Simpson's fiance is denying reports that she's pregnant.

"There is a witch hunt for people to be pregnant whenever they get engaged in Hollywood ... I mean we're engaged, that's true, and happy about it," Fall Out Boy frontman Pete Wentz, 28, told MTV News.

MTV News also said it asked Wentz if he was denying reports of Simpson's pregnancy. He answered: "Yeah."

OK! magazine and Us Weekly reported Monday that the couple is expecting their first child.

Simpson, 23, and Wentz announced their engagement last Wednesday.

Last week, Simpson's father, Joe Simpson, told People magazine he's "totally happy" and "so excited to have Pete as part of (our) family."

The pair began dating in fall 2006, according to People.

Simpson, a singer, songwriter and actress, is the younger sister of pop singer Jessica Simpson. Ashlee Simpson's new album, "Bittersweet World," is set for release on April 22.
