Matthew Morrison says 'The Greatest Dancer' bosses are keen for the dance captains to "bicker more".
The former 'Glee' star will line up on the panel of the BBC One show alongside Cheryl and Oti Mabuse, and while producers want the trio to do more squabbling between themselves, he insists they don't feel the need to do so because they get on so well.
He said: "Even between the dance captains, they were kind of saying you should bicker more between you.
"No. We don't feel that. We have such a bond, the three of us, and we're all there for the same reasons."
The 40-year-old singer-and-actor has enjoyed getting to know his fellow dance captains, and believes 'Strictly Come Dancing' professional Oti will be the "breakout star of the show".
He said: "Oti, I never knew her, but I think she's the breakout star of this show.
"Oh my gosh, [she has] so much energy. She's such a bright light and this is her first time being in a different role.
"She's usually the one being judged, so it's been fun getting to know her."
Matthew had already exchanged pleasantries with Cheryl when they starred opposite one another in 2012 movie 'What to Expect When You're Expecting', and admits it is "funny" that she portrayed a TV dance talent show judge in the motion picture.
Speaking on 'Lorraine', he added: "I knew Cheryl. We did a movie together called 'What To Expect When You're Expecting'. It's funny, because the opening scene of this movie, I play opposite Cameron Diaz, this unknown actress.
"It was a dance show setting and Cheryl was a judge, so she was giving her feedback.
"We only crossed paths and said hello."
