This is one baby that’s going to have good rhythm!  Professional dancers Allison Holker and Stephen t’Witch Boss welcomed their first child together – a son named Maddox Laurel Boss.

Holker shared the happy news on Twitter: “We had an EASTER BABY!! We welcomed MADDOX LAUREL BOSS to the world. 8 lbs 15 oz, and very healthy. He is surrounded by so much LOVE.”

The couple’s representative shared more of their comments with People: “[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!” adding, “Maddox already has the best big sister Weslie, they have already bonded and share a truly beautiful love.”

Holker and Boss met as contestants on So You Think You Can Dance.  Since then Holker has performed as a pro on Dancing with the Stars since 2014 and was the first woman to compete on DWTS while pregnant.  Boss continues to perform as a dancer and actor, and has been featured as the guest DJ on The Ellen DeGeneres show since 2014.

t’Witch and Allison became engaged after 2 1/2 years of dating, and married in 2013 at SYTYCD’s producer Nigel Lythgoe’s winery in Paso Robles, California.  They are raising Allison’s daughter, Weslie (7) from a previous relationship.
