Dancing into their hearts! Allison Holker and her husband, Stephen "tWitch" Boss have welcomed a baby boy, the couple confirms to Us Weekly. Their baby boy, Maddox Laurel Boss, arrived in L.A. on Easter Sunday.

Little Maddox weighed in at 8 pounds, 15 ounces, and measured 22 inches long. He now joins big sister Weslie, Holker's 7-year-old daughter from a previous relationship.

"[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 told Us in a statement. "Maddox already has the best big sister Weslie, they have already bonded and share a truly beautiful love."

The couple first met as all-stars during So You Think You Can Dance's season 7 in 2010. Three years later, they married at SYTYCD judge/producer Nigel Lythgoe's Villa San Juliette Vineyard and Winery in Paso Robles, California.

Us Weekly broke the news in October that Holker, 28, and Boss, 33, were expecting. They later gushed over the news during a live taping of Dancing With the Stars. Although she was pregnant, Holker stayed on the ABC series' season 21 to compete with her celebrity partner, Andy Grammer. (Holker is sitting out season 22.)
