Jenna Dewan is pregnant with baby No. 3, her second with Steve Kazee

Jenna Dewan is pregnant!

The “Step Up” star announced on Instagram Wednesday that she is pregnant with baby No. 3, which would be her second with fiancé Steve Kazee.

Dawan, 43, posted a video of Kazee, 48, serenading her as she took a bubble bath, covering her bare chest with her hands.

“Think if I make @stevekazee serenade me every night the baby will get his voice??” she captioned the clip.

In the sweet video, Dewan lounged in the water — with her belly peeking through — as the producer sat on a chair beside the tub with his guitar.

She also posted a separate clip of herself standing with her back to the camera before turning around, revealing her growing tummy.

The dancer put her belly on full display in a see-through, mesh dress as she cradled her burgeoning bump.

The short video, which was set to “I Wish You Love” by Sam Cooke, was filmed for her cover story with Romper.

Dewan told the outlet in an interview published Wednesday that she just entered the second trimester and already “feels alive again.”

She and Kazee, who have been engaged for four years, welcomed their first child together — a son named Callum — in March 2020.

“He’s so naturally domestic and nurturing, and he’s so loving, and he’s funny, and he’s really… he’s just incredible,” she said of the Broadway actor.

“It’s one of those things where people just have a natural ability for parenting. I’m so excited to see him with a little baby again.”

Although working on “The Rookie” while pregnant has been “exhausting,” Dewan said it’s also been an “amazing” experience and “helps balance [her] mind.”

Despite jumping right back into work after giving birth to her 10-year-old daughter, Everly — whom she shares with ex Channing Tatum — and 3-year-old Callum, Dewan said she might take it easy this time around.

“I’m not sure the body necessarily gets right back into action the way it did years ago. We’ll see,” she told the outlet. “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.”

The couple also decided that this would be their last child and have been cherishing every moment, which is why they decided not to find out the sex of their baby ahead of time.

“You don’t race to the end because this is the last time,” she said of their decision. “So there’s a bit of joy and a little sadness. I’m really trying to enjoy it all and not try to just get through the days.”
