Peta Murgatroyd is one hot mama-to-be!
The DWTS pro left little to the imagination as she bared her baby bump in barely there underwear for a sexy selfie on Instagram.
"Oiling this buttercup up," the 33-week-pregnant star captioned the racy pic.
Peta, 30, is expecting her first child, a baby boy, with fiancé Maksim Chmerkovskiy, 36.
"We couldn't be happier Baby Chmerkovskiy is coming," she wrote when she announced the pregnancy this past summer.
