Is Ashlee Preggers???

After announcing their engagement yesterday, rumors are circulating that Ashlee Simpson is pregnant with Pete Wentz's baby!

I guess it's the natural assumption when two people so young decide to get hitched.

If it were true, would a baby bump slow the couple's partying ways? -- I would sure hope so! These kids would have to get out of the clubs and over to Petit Tresor tout de suite!
