Ok! magazine and Us weekly have both reported that the reason for Ashlee Simpson and Pete Wentz’s recent engagement news was because Ashlee is pregnant.

But in an e-mail to MTV News, Wentz denied the reports.

“There is a witch hunt for people to be pregnant whenever they get engaged in Hollywood,” he wrote. “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.”

Asked again if he was denying reports that Simpson is pregnant, Wentz replied, “Yeah.”Ok! magazine claims that a source close to the couple has “proof” that the rumors are true.

On one occasion, Simpson seemed to be dealing with a “fierce bout of what appeared to be morning sickness” during a lunch at Malibu’s Chart House restaurant.

“Ashlee would like to walk down the aisle before she’s showing,” a source told OK! “Although she’s very cute the way she’s always checking out her belly now and asking everyone, ‘Am I showing yet?’ ”

On Monday, a spokesperson for the couple added fuel to the speculation by declining to confirm nor deny this week’s rumors. “We are thrilled to confirm their engagement and congratulate this happy couple,” the rep told MTV News. “Beyond that there is nothing to add.”

The couple released a statement about how happy they are about getting married, but failed to mention the pregnancy. Like we wouldn’t find out. I am sure that the pregnancy did not play a role in Pete’s decision to propose, right? If it was even his decision at all. I can imagine what controlling grandpa Joe had to say about the matter. Wow–who wouldn’t want to be a fly on the wall for that conversation!?! We all know Petey went straight to Gramps to ask his permission to marry Ashlee, but I wonder if they already knew about her little bun in the oven at that point….interesting….
