This was an unforgettable Halloween for Steve Kazee and Jenna Dewan, who are having a baby together. The Broadway actor couldn’t help but share his excitement in an Instagram photo he posted of his lady flaunting her baby bump on Thursday, October 31, which happened to be one day after his birthday.

“Things that go ‘bump’ in the night! My 44th Happy Halloween and baby Kazee’s first!” he wrote. “Thank you all for the birthday wishes yesterday. Best. Birthday. Ever.” In honor of his birthday, Jenna, 38, made sure to give her man a very special shout-out. “The world became a better place the day you were born … Your strength, gentleness, humor and caring beautiful soul touches everyone who knows you,” she captioned a series of photos of Steve, which included some silly snaps. “I am the luckiest girl in the world to love you and be loved by you. Happy birthday @stevekazee! (You’re going to kill me for the last shot, sorry.)”

The couple seem over the moon since announcing they’re expecting their first child together. Jenna already has a daughter named Everly from her previous relationship with ex-husband Channing Tatum. Thankfully, though, Steve and Everly have a great bond. When he confirmed the news that he is indeed going to be a father, he gushed about her in the sweetest way.

“Jenna also brought with her one of the greatest gifts one could ever imagine … her beautiful daughter,” the Once star wrote in September via Instagram. “Evie burst into my life like a supernova and has continued to burn so brightly in it. 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.”

What’s next for Jenna and Steve? Well, the pair is planning to purchase a new home for their growing family. “They’re looking for a bigger pad, with more space in the San Fernando Valley, so that the kids have more freedom to run around and play,” a source exclusively revealed to Life & Style. Happy house hunting, you two!
