Dancing With The Stars pro coach Allison Holker is pregnant with her second child. The talented So You Think You Can Dance alum revealed the big news during the Oct. 5 live broadcast of DWTS, which appropriately featured the celebrity contestants sharing their most memorable years via dance.

Holker, 27, first appeared before American Television audiences as a contestant on the second season of SYTYCD. She married husband Stephen 'tWitch' Boss, who also competed on the show, in December of 2013 after two and a half years together. The baby will be her first child with Boss; her daughter Weslie was born in May of 2008.

Dancing with the Stars season 21 is Holker's third as a pro coach.

She partnered Mean Girls star Jonathan Bennett to a ninth place finish during season 19, and placed second with singer Riker Lynch at the close of the star-studded 20th season in May of 2015. She is currently partnering Honey, I'm Good singer Andy Grammer, and is the first show pro to compete for the trophy while pregnant.

Other good news for DWTS pros

Holker's baby news is far from the first piece of happy news to come from the Dancing with the Stars pro cast in recent times. Season 19 champion Witney Carson announced her engagement over the weekend after long-time boyfriend Carson McAllister popped the question during a sunset beach proposal. Show judge and two-time Mirrorball trophy winner Julianne Hough accepted her own marriage proposal from her NFL-player boyfriend Brooks Laich over the summer, and pro Lindsay Arnold --who is currently partnered with train hero Alek Skarlatos-- married high school sweetheart Sam Cusick in June.

Although they're not yet engaged, even more show pros have enjoyed luck in love. Kym Johnson is still romantically attached to season 20 partner Robert Herjavec, who stars on ABC's Shark Tank, and pros Peta Murgatroyd and Maksim Chmerkovskiy rekindled their romance earlier in the year after some time apart.

The show airs Monday nights on ABC, and will crown a winner at season's end.
