Peta Murgatroyd is certainly comfortable in her own skin deep into her pregnancy.

The Dancing with the Stars pro shared a sexy and revealing selfie Thursday on Instagram of her baby bump.

"Oiling this buttercup up. 33 weeks," Murgatroyd, who won last season of Dancing with the Stars with deaf America's Next Top Model winner Nyle DiMarco, captioned the image.

In the photo, Murgatroyd appears fresh out of the shower and is only wearing a black bra and beige thong. Her hair is wet and slicked back.

The 30-year-old blonde beauty is expecting her first child with Maksim Chmerkovskiy, the bad boy of the Dancing with the Stars ballroom. He was already eliminated from Season 23 with his celebrity partner Amber Rose.

The parents-to-be got engaged in December 2015, confirmed the pregnancy in June and have been snapping adorable photos left and right of each other ever since.

Chmerkovskiy anticipates his fiancee will be an "amazing mom," according to Us Weekly, and he couldn't be more excited about becoming a dad.

"I'm ready!" he said back in September. "But I've been ready [to be a dad] since I was like 21. But now I know that I'm ready, I'm like, 'Thank God it didn't happen before.'"
