Jenna Dewan Welcomes Third Child: 'Our Family Is Now Whole'

Jenna Dewan is now a mom of three!

The actress and her fiance, Steve Kazee, recently welcomed their second child together and announced the big news on social media.

Dewan, 43, and Kazee, 48, welcomed their baby girl, Rhiannon Lee Kathryn Kazee, on June 14. The couple announced her arrival in a joint Instagram post on Thursday.

"From the moment you arrived, you have brought immense joy and love into our lives… your gentle grace, sweetness, and beauty have captivated our entire family," they wrote in their Instagram caption. "Our hearts are overflowing with love, and we are truly blessed by your presence. Welcome to our world baby girl."

In a short time, the post has received more than 115,000 likes and nearly 2,000 comments. Many friends and fans dropped into the comment section to share congratulatory messages for the family of five.

"So much beauty and perfection in such a little body!!" one person wrote. Another added, "Congrats! So happy for you too oh both! Lots of love."

Dewan shared a follow-up video on Instagram showing her other children, Callum, 4, and Everly, 11, meeting their new baby sister captioned, " & our family is now whole."

Many followers left comments congratulating the family on their new addition and some talked about how sweet it was seeing Callum and Everly with the new baby.

"I had to watch Evie and Callum again and again, it’s the sweetest," one person wrote. Another added, "Ohhhhh this completely melts me!! Seeing Callum and Ev with the baby is everything!!!"

At the beginning of the video, the hospital bassinet is shown with the baby's information, sharing that baby Rhiannon was born via C-section at Cedars Sinai weighing 7 pounds, 10.4 ounces.

Earlier this year, Dewan shared that her third pregnancy was a little different than her first two with PEOPLE.

"Third pregnancy while chasing two other kids around definitely makes you a little more tired," she said. "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."

Dewan also talked about how Kazee has been with the pregnancy.

"He is really good with cravings and also amazing with helping out with Eve and Callum with their schedules," she said. "And he's constantly reminding me to rest, which is really nice. He's amazing in that way."

Dewan recently opened up about co-parenting with her ex-husband Channing Tatum, who she shares daughter Everly with, as well as what it's like blending families.

"Like everything else in life, you learn as you go. You shift and evolve and you adapt to how life is presenting itself to you," Dewan told PEOPLE. "That includes getting the new normal of a blended family. Kids come first. How you feel about your kids. How you treat your kids. Kids always come first above everything else."

Dewan always knew she wanted a big family, so reentering motherhood in her 40s was something she welcomed.

"It feels like I always knew that this would probably be the path for me, even as a kid," she said. "I think I knew life got better as I got older if that makes sense. I'd never understood that like, 'Oh no, it's all over once we get older.' Life's only shown me that the more time I have in this life, the more I've learned, the better experiences I've had. Everything just kind of feels better."

Dewan uniquely shared her pregnancy announcement with a video on Instagram that showed her growing baby bump in the bathtub as Kazee serenaded her captioned, " Think if I make @stevekazee serenade me every night the baby will get his voice??"

Kazee dropped into the comments to say, "I’d have a million babies with you!"

Many followers also left comments for the expectant mom.

"Wait. What? Omg! Congrats!!" one person wrote. Another added, "Congratulations mama!!!!!! I LOVE this and am so happy for you."

Dewan told Romper that she was excited to see Kazee with another baby.

"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. "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."
