Boyzone's Ronan Keating has dismissed rumours that he is set to appear on Celebrity Big Brother on Britain's Channel 5.

Keating tweeted that he is "Loving all the chat about me going on Big brother. It's obviously not true as I am in @OnceMusicalLDN till March 21st."

He is one of several names been tipped by the tabloids to appear on the show, which begins in the next few days, including agent provocateur Katie Hopkins, Perez Hilton, Mel B's husband Stephen Belafonte, and Patsy Kensit.

Host, former X Factor contestant Rylan Clark, told  "We've got a very, very strong line-up . . . We're trying to steer away from reality stars but there may be one.

"Maybe not one that's very well known, it's not your usual line-up!"

American model Cami Li and former X Factor contestant Marcus Collins are also said to be CBB bound.
