Chmerkovskiy proposed Saturday during a performance of SWAY: A Dance Trilogy at the Olympia Theater in Miami - getting down on one knee and saying, "I'm in love with you, and I want to be in love with you for the rest of my life," in front of the audience, and a line of other dancers.
Murgatroyd said yes, and both then shared the special moment on Instagram.
This will be the first marriage for both. Chmerkovskiy was previously engaged to fellow Dancing pro Karina Smirnoff.
