Maksim Chmerkovskiy has so much love for his "queen!"

"After a long day of meetings and other events, this is what happens," Chmerkovskiy exclaimed, panning the camera to Muragtroyd, who was dressed in strappy black heels and sitting on the floor. "Babe."

"I'm too big to get up!" she joked.

Chmerkovskiy's caption for the video was equally cute.

"When queens get tired they sit down....wherever they can!" he wrote. "@petamurgatroyd put up a good fight, but #babyChmerkovskiy always wins ? #FourMoreWeeks #InLoveWithThisChick."

The post comes just one day after the adorable duo -- who are expecting their first child, a baby boy, together -- celebrated the one-year anniversary of their engagement. Chmerkovskiy proposed to the 30-year-old dancer last Dec. 5 onstage at his Sway: A Dance Triology show in Miami, Florida.
