The "Knocked Up" sequel "This Is 40" hits theaters on Dec. 21, and the cast stepped out in Hollywood on Wednesday to attend the premiere.
New mom Megan Fox stunned in a dark red wrap dress with black stilettos. The actress, 26, gave birth to son Noah on Sept. 27. Just 10 weeks later she looks amazing (no surprise there!)
Newly single Danica McKellar, who filed for divorce over the summer, looked cute in a purple and silver off-the-shoulder frock.
Heather Locklear was accompanied by her beautiful 15-year-old daughter Ava Sambora, while Leslie Mann looked slim and trim in a white gown with an orange patterned neckline.
