Jenna Dewan 'Feels Her Family Is Complete' After Giving Birth to Baby No. 3

Jenna Dewan is happier than ever after giving birth to daughter Rhiannon on June 14.

“Jenna feels so blessed to have this family,” said a source of the Step Up star, 43, who shares son Callum with her fiancé, Steve Kazee, 48, in addition to daughter Everly with ex Channing Tatum.

“Steve was wonderful during the whole thing, stroking her forehead, holding her hand. Jenna was calm for the most part, and when she got to hold the baby for the first time, she was overcome with love and gratitude," they added of the actor being supportive during the birth.

Though the little one has only been around for a short while, the brunette beauty has “loved seeing her older kids with Rhiannon. She feels her family is complete," the insider added.

Prior to giving birth, The Rookie star spoke about how she's adjusted to motherhood over the years.

"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," she told People. "That includes getting the new normal of a blended family."

When Dewan learned she was pregnant, her two kids were excited to welcome another member into the family.

"[Everly] is the oldest, so she gets it the most. And I think because she was still so young when Callum was born, this will be really special for her," Dewan noted. "She's just going to have more responsibility, but she's also going to have more wisdom to her."

"It feels like I always knew that this would probably be the path for me, even as a kid. I think I knew life got better as I got older if that makes sense," she added of being a mom. "I'd never understood that like, 'Oh no, it's all over once we get older.'
