'DWTS' Allison Holker, husband Stephen 'tWitch' Boss reveal baby's gender

LOS ANGELES, Dec. 11 (UPI) -- Dancing With The Stars pro Allison Holker and her husband, dancer Stephen 'tWitch' Boss have revealed on Instagram the gender of their baby.

Boss shared the news that the couple will be having a boy Thursday when he posted a photo of himself and Holker holding a blue layered cake commonly used at gender reveal parties.

"It's a boy!!!! #BabyBossboy Surrounded by so much love today!!! Life is beautiful, he captioned the post before also sharing a sentimental throwback photo of the couple on their wedding night.

"Two years ago our journey became one. Two individuals forming a family unit. @allisonholker You're truly my better half and even though we annually honor our wedding day, it's truly our everyday process that makes our relationship special. It's those other 364 days that makes this one that much better. Growth, inspiration, love, and good memories make us the Boss family. And babe I can't wait to celebrate many more..........with many more," Boss wrote on the heartfelt post.

The baby boy will be the first child for the couple, who tied the knot in December 2013. Holker has a 7-year-old daughter named Weslie from a previous relationship.

Holker, also known for her time on So You Think You Can Dance, famously announced her pregnancy back in October when she was backstage with singer Andy Grammer getting ready for a performance on Dancing With The Stars.

The next day, Boss appeared on The Ellen DeGeneres Show where the comedian teased the dancer with a comedic ultrasound video that featured his unborn baby dancing in the womb.
