Stephen "tWitch" Boss and Allison Holker have got the moves.

Boss stepped away from his DJ booth and took the reins as the guest host ofThe Ellen DeGeneres Showon Friday.And, naturally, he kicked things off in trueEllen DeGeneres fashion: By dancing it out. Of course, he added his own spin to the routine, bringing out his wife ofnearly six years, who also happens to beverypregnant.

"My best advice is to find a dance partner that you trust and you love," Boss said to the audience."And for me, that's my beautiful wife Allison. She is nine months pregnant, she is my hero and she is here. And we're about to groove like onlyBosses can do."

The expectant parents proved to be an absolute mood as they rocked out toNormani's "Motivation." Throughout, they both took pride in flauntingHolker's bump. If watchingher dance so joyously while nine months pregnant doesn't motivate you today, nothing will!

TheSo You Think You Can Dancealums will soon welcome a third tiny dancera baby girlto their brood.Holker is mom to daughterWeslie, 11, and theduo share sonMaddox, 3.

"Can't even express all the incredible emotions we are feeling right now!" she wrote on Instagram after their gender reveal. "I am so excited to be bringing in another beautiful baby girl into the world...This baby girl is already surrounded by love and support!"
