Her beefy BF Joe Manganiello was nowhere to be seen, but to paraphrase the great Elvis Presley: if you can't find a partner, use a pro!

But while Derek Hough was tilting and dipping her, it looks like her nip came popping out of her dress!

Since September 2007, Hough has become known for his work on the ABC dance-competition series, Dancing with the Stars, on which he has won a record six seasons.

With a total of eight nominations, he has won two Primetime Emmy Awards for Outstanding Choreography for several routines that he choreographed for the show.

Derek has also been rumored to have romanced Lauren Conrad, Nina Dobrev and Nikki Reed in the past.

News broke of Kate and Matt's split on Monday, when his rep confirmed that the two have been separated "for some time now," after four years together.

When Hough was 12, his divorcing parents sent him to London to live and study with dance coaches Corky and Shirley Ballas.

After spinning onstage at the Emmys, she went for another spin at the HBO after party– on the dance floor!

But after eight years together he reportedly broke up with her to start dating his DWTS season six partner Shannon Elizabeth.

It's likely Elizabeth's fault that he would be linked with nearly every partner after her.

Once people knew he was capable of dating someone and lying about it, it was easy to assume he'd doing the same with all his dancing partners. He's still friends with Elizabeth and the pair caught up over dinner in 2012.

As of 2014, he has held a recurring acting role on ABC's musical-drama, Nashville.

On December 7, 2016, Hough played the role of Corny Collins in NBC's live musical TV-production, Hairspray Live!
