Maksim Chmerkovskiy is taking his duties as a first time father seriously.
The 36-year-old Dancing With the Stars pro is expecting his first child with fiance Peta Murgatroyd, and on Wednesday, Murgatroyd shared a hilarious Instagram pic of her man tying a baby shoe. Chmerkovskiy shows off his chiseled physique in the snap, going shirtless and rocking nothing but a pair of Calvin Klein boxers and trouser socks.
"Someone's getting prepared #babychmerkovskiy," Murgatroyd wrote.

Chmerkovskiy posted his own version of the cute event on Instagram, joking, "Was sitting here, innocently practicing for #babychmerkovskiy and totally got used for followers by @petamurgatroyd. So here's hoping this one gets more likes than hers."
But sorry Maks! Murgatroyd's shirtless snap got over 10,000 more likes than his own post as of Thursday morning.
ET confirmed the couple was expecting their first child together in May. The professional dancers have been engaged since last December.
"They're so happy," a source told ET about the exciting baby news. "Funny thing is, they've been trying to get pregnant even before they were engaged."
Murgatroyd, 30, is now in her second trimester, and is expecting to give birth in January.
