The gorgeous actress was spotted in L.A. last night, looking like she's already back to her pre-baby weight less than two months after giving birth.
Sporting super-tight jeans, a black shirt, Christian Louboutin heels and a black blazer, Fox was seen going to a screening of her new movie, "This Is 40."
Hard to believe she popped out a kid at the end of September, right?
Fox and husband Brian Austin Green welcomed their first child together, son Noah Shannon Green, on September 27.
"He is healthy, happy, and perfect," Fox said on her Facebook after Noah's birth. "We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love."
