The third trimester has arrived for Peta Murgatroyd!

The professional dancer, who is expecting a little boy in early January with fellow pro dancer Maksim Chmerkovskiy, posted a mirror selfie Friday showing the mom-to-be’s bare baby belly accompanied by a lacy black bra, chic updo and full makeup.

“Bump watch!! #babychmerkovskiy will be here in no time!” she captioned the photo, adding a smiling-baby emoji.

Their son will be the first child for the Dancing with the Stars pros, who were engaged in December and are planning a summer 2017 wedding. The couple revealed their baby news in June, sharing that they were expecting a boy in August.

The expectant mama made an October appearance at PEOPLE’s Ones to Watch event, looking every bit the fall fashionista in a black lace number, matching choker and long, dangling earrings while gracing the red carpet.

The father-to-be, who will not be returning for DWTS‘ 24th season, is looking forward to taking a well-deserved break to focus on his growing family.

“For me to be able to take time off in this way … [to have] what we have to enjoy and be proud of, that’s anybody’s dream,” Chmerkovskiy told PEOPLE in August after being eliminated from the current season of DWTS alongside partner Amber Rose.
