Inside Maksim Chmerkovskiy and Peta Murgatroyd's castle wedding

The "Dancing with the Stars" professional dancers wed Saturday.

— -- Meet Mr. and Mrs. Chmerkovskiy!

At the reception, Chmerkovskiy, 37, not only showed off his dance moves, but his vocal ability. The groom serenaded his bride as his friends danced behind him.

In a speech, the bride said, "This has been literally the best day of my life...this is so amazing."

Chmerkovskiy told ABC News ahead of his big day that he picked Oheka Castle to marry Murgatroyd, 30, for a very special reason. It was actually a full circle moment for the Ukrainian professional dancer, who moved to Brooklyn in 1994.

"I remember when I was passing by this castle when I first immigrated, and [I said] 'That's where I want to have my wedding' and I just said it so [casually] and now it's happening," Chmerkovskiy said back in March.
