Pregnant Jenna Dewan Shows Off Baby Bump in Bra and Shorts as She Jokes About 'Bed Head' Hair

Jenna Dewan is showing off her baby bump!

On Sunday, April 28, the Step Up actress, 43 — who is expecting her third baby, her second with fiancé, Steve Kazee, 48 — posed in a white bra and a pair of matching shorts as she joked about her appearance in a post shared to her Instagram Stories.

Dewan's growing belly was on full display as she pointed to her messy hair that covered her face in the selfie. "Bed head," The Rookie star wrote over the shot.

Dewan's post came after she said Kazee had been nothing short of "amazing" while they wait for their latest family member's arrival.

While speaking to PEOPLE on April 23, the actress said, "He is really good with cravings and also amazing with helping out with Eve and Callum with their schedules," referencing her and Kazee's 4-year-old son and her 10-year-old daughter Everly, whom she shares with her ex-husband Channing Tatum, 44.

"He's constantly reminding me to rest, which is really nice. He's amazing in that way," Dewan added.

"When I was a kid, I always had this vision — it was so specific. It was the Christmas tree around Christmas, and just kids and family and just chaos. Happy chaos all around," Dewan, who grew up as an only child, continued. "And I realized the other day, I was like, oh, in my own way, I am creating [that]. So that's exciting for me."

The actress also noted she's feeling "great overall," but admitted she's been "more tired" than usual.

"Third pregnancy while chasing two other kids around definitely makes you a little more tired. I find crawling into bed at 9 p.m. is definitely different this pregnancy. But overall, everything's been going well. And it's been wonderful. But I’m without a doubt a little bit more tired," she shared.
