Megan Fox Post-Baby Body Pictures on The Tonight Show

Megan Fox stopped by The Tonight Show last night to chat about her latest film, This Is 40. She wore a figure-flattering blue Roland Mouret dress that showed off her post-baby body. Megan gave birth to her baby boy, Noah Green, three months ago, and while chatting with Jay Leno last night, she jokingly shared concerns that Noah was not the average baby. "I was convinced that I was, like, maybe birthing a vampire baby like the one in Twilight — you know what happens to Bella, where she's in cold sweats all the time."

Megan also revealed that the last time she stopped by The Tonight Show, she was actually trying to hide her growing baby bump. "I was about two months pregnant. I was really sick." Fortunately, Megan made it through the rough patch and went on to describe the pregnancy as "perfect." Now the first-time mum, and stepmum to her husband Brian Austin Green's son Kassius, is enjoying motherhood and celebrating the release of her comedy with Leslie Mann and Paul Rudd.
