"Becoming a mother is quite simply the absolute best most incredible thing that has ever happened to me," Jenna, 38, wrote alongside an adorable photo of her rocking a plump belly while lying in bed with her 6-year-old daughter Everly. "Steve Kazee you are a gift from above and I couldn’t be more excited to be expanding our family together! Thank you guys for all the love!!"
As fans know, Jenna and her ex-husband Channing Tatum welcomed their little girl in May 2013.
Steve, 43, also took to social media to share his excitement over his first child!
"Well...the news is out. I can’t even begin to describe the feelings that I have had since we first learned that Jenna was pregnant!" The Shameless actor captioned a photo of Jenna wearing a cheetah dress and holding her belly. "I have waited my entire life for this moment and couldn’t have found a better person to build a family with."
"The past year and a half has brought so many things into my life that have filled me with the deepest of gratitude. A partner who radiates love, warmth, and kindness. A partner who has faced some of the hardest moments life can deal you with grace, humility, and a desire to learn from the ups and downs," he added.
"A partner who is continuously growing from those lessons and who supports my growth as a person with love, unwavering support, and understanding," Steve continued. "Jenna also brought with her one of the greatest gifts one could ever imagine...her beautiful daughter."
"Evie burst into my life like a supernova and has continued to burn so brightly in it," he said. "I have learned so much about parenting already from watching how amazing Jenna is with her and Evie has taught me so much about what it means to love and communicate with a child and I can’t wait to give her a sibling and make our little family a little bit bigger."
As fans know, Jenna and Steve’s relationship first broke news in October 2018 — a few months after the America's Got Talent host and Channing, 39, announced their separation. The Magic Mike star, who is also seriously dating singer Jessie J, is reportedly "really happy" for his ex-wife.
“For a couple who announced they were divorcing a little over a year and a half ago, everything seems to be going as smoothly as can be expected,” a source told In Touch on September 25. “Jenna and Channing have definitely uncoupled better than most.”
“The good news is that Channing likes Steve, so he knows that Jenna and their daughter are in good hands," the insider added.
