Dancing With the Stars sweethearts Maksim Chmerkovskiy and Peta Murgatroyd will probably have to start rehearsing their wedding dance soon.

Chmerkovskiy proposed on the DWTS dance floor on Saturday, right after a performance of Sway at the Olympia Theater in Miami. Murgatroyd, 29, was surprised when Chmerkovskiy, 35, got on his knees and popped the question in front of the audience and other dancers.

“I’m in love with you, and I will be in love with you for the rest of my life,” Chmerkovskiy told his soon-to-be-wife. Then he presented Peta Murgatroyd with a lovely custom-made Cantamessa engagement ring, which he designed especially for his fiancée.

“Maks’ romantic proposal is something I will cherish for the rest of my life,” Peta Murgatroyd said of Chmerkovskiy’s proposal. In a brief interview with People she said that she is excited for the next chapter of their lives together and that she can’t wait to plan for her dream wedding with him.
