It's an Easter baby for Allison Holker and Stephen "tWitch" Boss!
The Dancing With the Stars pro and her husband, who regularly DJs on The Ellen DeGeneres Show, welcomed their first child together on Sunday, a baby boy named Maddox Laurel, ET confirms. He weighed 8 lbs., 15 oz., and measured 22 inches long.
"[Maddox’s birth] was truly an unforgettable moment and we are grateful to everyone that shared in the experience and made it so monumental. Our family feels full!” the couple said in a statement.

Holker, who met tWitch during So You Think You Can Dance's all-stars season in 2010 and married him in 2013, already has a 7-year-old daughter, Weslie, from a previous relationship.
"Maddox already has the best big sister Weslie," the duo added. "They have already bonded and share a truly beautiful love."
Holker surprised tWitch with a flash mob to reveal that they were having a boy, and then the couple shared the news with the world with an adorable gender reveal cake.
ET recently spoke to Holker about missing this season of DWTS and how "very sad" she is that Julianne Hough is leaving the show.
