Jenna Dewan is going to be a mom again!

On Wednesday, the Witches of East End actress, 43, revealed that she is pregnant and expecting her third baby by sharing a video on her Instagram. In the Reel, Dewan's fiancé Steve Kazee plays guitar and sings as he sits in a chair by the bathtub.

Laying in a bubble bath, Dewan moves the camera to show her bare bump, smiling as she listens to Kazee sing.

"Think if I make @stevekazee serenade me every night the baby will get his voice??" she wrote in her caption.

Dewan is already mom to son Callum, 3, whom she shares with Kazee. She also shares her 10-year-old daughter Everly with ex Channing Tatum, 43.

In December, the actress shared a hilarious video on Instagram, taking fans behind the scenes of her Christmas photo shoot — which didn't exactly go to plan.

In the clip, Dewan, Kazee, Callum, Everly and the family's four dogs all adorably dressed in matching red and white plaid pajamas. A professional photographer was on hand to take holiday photos of the group.

When it was time to get a family shot on the couch by the Christmas tree, Dewan faced a bit of a struggle. The Rookie star attempted to hold and wrangle Callum, who was crying.

As Dewan, Kazee and Everly made silly faces for the camera, Callum wailed away. In another cut, the family smiled as they posed and it seemed they almost got the perfect shot.

"‘Twas a good time had by all 😅," Dewan joked in her caption, poking fun at the exhausting efforts of trying to get everyone in sync for a photo.

Although they might not be great at family photoshoots, Dewan's daughter Everly has been working on a new skill this past year.

Speaking with PEOPLE exclusively in August, Dewan shared that her daughter Everly had been trying her hand at makeup. "She's been in a makeup trailer with me at work since she was...I have pictures of her 6 weeks old with me because I was filming Witches of East End and she was in the trailer with me," Dewan said of her daughter being around makeup artists.

"So she's just been around it. There's a part of her that's kind of interested, but she's really good. She has a little play set of makeup that I've been giving her and she's got a great look."

"I'm going to actually have her do my makeup. That's a great idea. It's playful for her. She's still 10, so she's young and she is enjoying other things, but she will have fun with it for sure. She loves glitter eyeshadow, which I do too. So it comes naturally," the star told PEOPLE.
