Former X Factor winner Shayne Ward believes the TV talent show "needed shaking up".
The 26-year-old singer - who won in 2005 only to be dropped by Simon Cowell's record label earlier this year - is looking forward to seeing the new judging panel with Tulisa Contostavlos, Kelly Rowland and Gary Barlow joining Louis Walsh.
Shayne, who stars in new musical Rock Of Ages, said: "I think it needed shaking up and I think the new panel will do that."
He added: "I'll definitely watch it, I'll have to record it because I'll be singing in the show but I've always been a fan of the X Factor and that won't change."
Shayne is set to star in the West End as rocker Stacee Jaxx, the same part that Tom Cruise is playing in a new movie adaptation of the musical.
But the singer insisted he was not worried about being overshadowed by the Hollywood star.
He said: "It is a great thing for me and a great thing for the part too that he is playing it.
"You wouldn't think it but, to me, he is perfect for the role. Look at when he was the big manager guy in Tropic Thunder, no-one even knew it was Tom Cruise and then when everyone realised it was him they all said he was amazing."
Rock Of Ages is set in the 1980s Los Angeles rock scene and features songs by bands including Journey, Bon Jovi and Twisted Sister.
The musical opens in September at the Shaftesbury Theatre in London.
