Derek Hough to perform on 'Dancing with the Stars' in October with girlfriend Hayley Erbert

Derek Hough isn't just judging this season of "Dancing With the Stars" -- he's putting on his dancing shoes.

The 35-year-old will pull double duty on the Oct. 19 episode by performing in the ballroom with his girlfriend -- and fellow "DWTS" pro -- Hayley Erbert, 25.

"I'm very, very excited," Hough said Wednesday during ABC's virtual fall press panel. "I'm even more excited to be dancing with my lovely girlfriend, my love."
