Megan Fox welcomed her son, Noah, with husband Brian Austin Green in late September. But only two months later, Fox showed off her post-baby body earlier this week. She hit a private screening of her new movie, This Is 40, in Beverly Hills and looked phenomenal in simple jeans, a blazer, and heels.

Fox, 26, broke the news of her son's arrival via Facebook Oct. 17—her son was born on Sept. 27. "He is healthy, happy and perfect," Fox said. "I am forever grateful to God for allowing me to know this kind of boundless, immaculate love."
