Unlike Gwen Stefani, Jennifer Lopez, and Christina Aguilera, who all toured while preggers, mommy-to-be Ashlee Simpson is putting her summer tour plans on hold. "After careful consideration, Ashlee Simpson has decided to postpone her summer tour," her rep said in a statement. "She is committed to giving her fans the best show possible, and will be back better than ever and ready to rock in the future." Yeah, it's pretty hard to lip-sync when you're with child. (Sorry! We had to do it.)

In related news, Pete Wentz recently e-mailed MTV to apologize for lying about Ashlee's pregnancy. Here's what he said:
"Every woman, no matter who they are or what they do for a living, has the right to wait at least three months before sharing this very personal news. We wanted to wait until after the first trimester and get a clean bill of health from our doctors before confirming anything, just like any other couple. Being a boy, I have no idea how to respond to such things and my first instinct was to protect her and the baby. It's insane that you can't let happy news brew in Hollywood. This wasn't about press or anything. It was about the health of the baby and trying to find a way to be happy with what should be the most happy time of our lives in the middle of a press blitz. I apologize to anyone who felt misinformed but the truth is, the person and growing baby is who I felt most loyal to protect and defend."

We've gotta say that we actually agree with him in a way. But if you don't want the news getting out, don't tell untrustworthy friends! It's the price of fame, dude.
