This Morning host Matt Johnson said he does not mind which celebrity he has to impersonate in a new singing show - as long as they are Welsh.
The Caerphilly-born presenter is one of six celebrities lined up to perform in Your Face Sounds Familiar.
The ITV show, presented by Alesha Dixon and Paddy McGuinness, challenges the celebrities to transform themselves into a different singing star chosen at random each week.
He said: "My ideal would be the Sterophonics because I struggle trying to mimic other accents and dialects and I always sound Welsh so Bon Jovi for the first few weeks was very Welsh, Jon Boyo Jovi."
Alexander, who will perform as country star Johnny Cash on the opening night, said he was looking forward to "six weeks of karaoke". But he said he was slightly worried about the reaction from the panel of celebrity judges especially Julian Clary.
He said: "I heard him being briefed by someone that it was felt that he could, if he wanted to, have an edge to his opinions and that would be very much appreciated. Though I don't think he needs any encouragement in that direction.
"Julian is as you know a master of innuendo, lord knows what he will make of a ring of fire."
None of the contestants will be evicted from the show. Instead they are scored on a leader board with the winner at the end of each show getting a cash prize for a charity of their choice, with a further grand prize pot for the series champion.
