Peta Murgatroyd is 30! The Dancing With the Stars pro celebrated the milestone birthday in style with fiancé Maksim Chermkovskiy by her side.

Chmerkovskiy, who proposed in December, spent Thursday spoiling his future wife in Cincinnati, where he is currently on tour.

The Australian native, who is expecting her first child with Chmerkovskiy, gave her man a sweet kiss as they posed in front of her birthday cake and said goodbye to her 20s.

The cake was adorned with blue writing and baby blue baby booties, which naturally leads one to wonder if the parent-to-be might be having a baby boy!

"? Cake and Kisses for 3 @maksimc ?," Murgatroyd captioned the sweet shot.

The DWTS couple ended the night with cake, but they kicked off Murgatroyd's "Dirty 30" with a breakfast spread fit for a queen.

"Birthday breakfast with my favorite! ❤️?? #dirtythirtyneverlookedbetter," Chmerkovskiy captioned the photo of his fiancée sitting on the bed wearing a sideways hat and sweats.

After having breakfast brought in, the pair got dressed up for their big night out. Murgatroyd showed off her growing baby bump in a sexy crop top and sleek black pant combo, while Chmerkovskiy sported a black button-down shirt, khaki pants and black sneakers.

"Happy birthday @petamurgatroyd ❤," the 36-year-old Ukrainian dancer captioned a couple selfie.

"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," he added.

The birthday girl shared a photo of herself as well, showing off her bouquet of roses as she gave the perfect side eye to the camera.
