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

Hough has won "DWTS" six times and is currently a judge for season 29.

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."

The six-time Mirror Ball champion competed as a pro for 17 seasons between 2007's season 4 and 2016's season 23 and has more wins than any other pro.

Throughout the years, Hough won "DWTS" with celebrity partners Brooke Burke, Nicole Scherzineger, Jennifer Grey, Kellie Pickler, Amber Riley and Bindi Irwin.

This year, for season 29, the two-time Emmy winner is filling in as a judge for Len Goodman, who was unable to travel to Los Angeles from the United Kingdom due to COVID-19.

"Dancing With the Stars" airs Mondays at 8 p.m. ET on ABC.
