Seems like getting knocked up is THE most popular trend in Hollywood these days, right behind Balenciaga bags and wide-leg jeans. The latest starlet to jump on the baby bandwagon? None other than the newly-engaged Ashlee Simpson!? Us Weekly is confirming that the singer is pregnant, through an exclusive source (Jessica Simpson, we are on to you!). We’re not sure how this will affect Ashlee’s upcoming album – dropping the same day as Mariah’s on April 22 – but hey, if Gwen can tour while pregnant, anyone can! Congrats are in order to the happy couple, obvs. Their future offspring is so lucky – it already has a crazy aunt!
