The hilarious Alyson Hannigan shares something big in common with her character on the hit comedy, How I Met Your Mother — both are pregnant! But as Alyson tells Rachael, her character got a bit of a head start. "Lily got pregnant first, I guess at the last season's finale," she says. "Then I said [to my husband], 'Honey, we have this summer to work on it!' And since my character was farther along than I was, at times I had to wear a pad over my bump, which was pretty uncomfortable. As I got bigger, they took the pad away. So if you see my belly button [on the show], that's me, and if I don't have a belly button, that's the pad!"

Moviegoers will be able to see Alyson return to the big screen when she reunites with her American Pie co-stars for American Reunion. Enter here for a chance to win a Blu-ray/DVD copy of the 1999 smash comedy!
