Michael Bolton is preparing for a tense face-off with U.S. TV personality Bruno Tonioli when the two meet up again on Tuesday night's (05Oct10) Dancing With The Stars.
Bolton has stepped in to replace a sick Susan Boyle on the results show - just a week after he was voted off the programme.
The crooner took aim at show judge Tonioli, demanding he apologise for harsh comments he made about Bolton's dancing - but the choreographer has refused, setting up a ratings-winning showdown on Tuesday.
On last Monday's (27Sep10) episode of the celebrity talent show, Tonioli ripped into the When a Man Loves a Woman singer after his performance with professional dance partner Chelsie Hightower, insisting it was the "worst jive" he had seen in 11 seasons of the hit programme.
Bolton was visibly shaken up by the criticism and didn't even hang around to speak to the press after he was voted off the show on Tuesday night (28Sep10).
Demanding Tonioli apologises to him and Hightower, Bolton said, "He let everybody down. I think he should apologise publicly and he should be reprimanded.
"My mom was there, she flew in, she's 90 and she came to see a show and I thought she was really gonna enjoy it and I just didn't expect that level of disrespect from him."
