Dancing With the Stars pro Peta Murgatroyd celebrated her 30th birthday with fiancé Maksim Chmerkovskiy Thursday, and may have revealed her baby's gender in the process!

The dancer, who is currently pregnant with her and Chmerkovskiy's first child, can be seen on her Instagram giving her fiancé a smooch next to a cake featuring blue writing and a pair of blue baby booties, leading fans to speculate that the talented pair may be having a boy.

"Cake and Kisses for 3," Murgatroyd wrote.

Chmerkovskiy also documented his fiancée's milestone birthday on his own Instagram, starting with a shot of the birthday girl eating breakfast in bed, presumably in Cincinnati, where he is currently on tour with his brother Valentin.

"Birthday breakfast with my favorite!" he wrote.

He later followed up with a shot of the couple as they prepare to head out, with him wearing a black button-down and khakis while Murgatroyd sports a black crop top and pants ensemble.

"Happy birthday @petamurgatroyd," the 36-year-old captioned the shot. "I can't wait to tell our kids stories about these pictures and I don't know how you manage to get hotter every day, but I am infinitely more attracted to you now then ever before! And 30s are so much better than 20s! Trust me...I know 😘 #dirtythirtyneverlookedbetter."

Murgatroyd also shared a photo of herself giving the camera some serious side-eye, with her growing baby bump on full display.

"That #dirtythirty side eye," she captioned the sultry snap.

Chmerkovskiy finished off the photos for the evening with an artsy shot of the remnants of Murgatroyd's bouquet of roses, writing "That's a wrap... Welcome to the thirties @petamurgatroyd #dirtythirtyneverlookedbetter #ourwaytour."
