The 'Ru Paul's Drag Race' resident choreographer will take a seat alongside dance captains Cheryl, Oti Mabuse and Matthew Morrison on the upcoming second series of the BBC One show after producers decided to "tweak" the format when questions were raised about the availability of the former 'Glee' actor.

A source told The Sun newspaper's Bizarre TV column: "At one point it looked like Matthew's schedule might mean he wouldn't return then bosses decided they wanted to add a fourth captain.

"They were really impressed with Todrick and decided to tweak the format slightly."

Cheryl confirmed in June she'd be returning to the show, which sees performers compete for £50,000 and a chance to perform on 'Strictly Come Dancing'.

She said at the time: "I don't think I'm allowed to say but I'm going to anyway - I'm going back to the dance show. I'm going to get told off for that, but it doesn't matter because it's just a fact. I love, love, loved the dance show."

As well as judging and coaching the competitors, the captains were also given the chance to showcase their dance skills as they performed a routine at the start of every show and then choreographed and took part in their contestant's number during the final.

Host Jordan Banjo said last month: "Cheryl brought so much to the show as a dancer and dance captain. She was wicked to work with and handled everything really well. Her performance with the Strictly pros was like a baptism of fire. Getting on stage with them at world-class level and holding her own, she smashed it."
