The 40-year-old ditched her usual jeans-and-tee get-up for a tight red dress as she strutted the red carpet for The Odd Life of Timothy Green with Aussie co-star Joel Edgerton.
You'd be forgiven for thinking Jen never gave birth to her third kid just five months ago. Baby belly? What baby belly?
While Jen is clearly in shape, we're relieved to see the 40-year-old has kept her famous curves rather than succumb to the dreaded size zero. It's refreshing to see a woman look like … well, a woman!
The actress, who seems to have marriage down pat with her hubby of seven years Ben Affleck gave birth to the couple's first son Samuel in February.
They also have two daughters — six-year-old Violet and three-year-old Seraphina.
Watch Jen ooze confidence on the red carpet in the clip above.
