Last month, the mom of two shared a series of photos of her pregnant belly on Instagram as she posed in her dressing room for a mirror selfie. In the first photo, Dewan bared her bump as she wore a two-piece sweat set.

The star also included several other shots of herself from the side and in her underwear as she captured her growing belly throughout her pregnancy journey.

"Bring your bump to work edition," Dewan wrote in the caption.

In a recent interview with Romper, the Step Up alum revealed that she is pregnant with her third baby and opened up about how her pregnancy is different this time than it was when she was expecting her first baby at 32.

"I'm not sure the body necessarily gets right back into action the way it did years ago," she shared. "We'll see."

"I'll report back, but I do think there's a bit of ignorance, this dancer in me that just says, 'OK, well, you just get it done.' I've recovered great every time, but I'm open to whatever happens."
