Boyzone have blasted Blue for refusing to dance at their reunion shows.

Ronan Keating - frontman of the Irish boy band - criticised the 'One Love' hitmakers for disappointing their fans by choosing a less strenuous routine when they reunite at the weekend.

He said: "It's a cop-out if you ask me. Fans are going for the nostalgia and so they will want to see Blue pulling out the dance moves."

Blue - consisting of Lee Ryan, Duncan James, Antony Costa and Simon Webbe - are due to perform at Capital FM's Summertime Ball at the Emirates Stadium in London on Sunday (07.06.09) after a four-year break.

Ronan has offered to teach the British band some last-minute dance moves to help improve the show.

He added to Britain's Daily Star newspaper: "Send the lads over and we'll show them our moves. We all had to get super-fit because we're up on stage for two hours. It's hard work but you have to give people what they want."

Meanwhile, Boyzone - also consisting of Stephen Gately, Shane Lynch, Keith Duffy and Mikey Graham - have been exerting themselves to the point of embarrassment on their current 'Back Again... No Matter What' tour.

Stephen revealed: "During my solo routine of Beyonce's hit 'Single Ladies' I do all of the moves that she does in her amazing video.

"I was bending over and suddenly felt my trousers rip at the back. I shuffled off stage at the end carefully trying not to turn around."

The Irish group are currently working on a new album which they hope to release later this year.

Stephen added: "We're still looking for the right producer. I'm a massive fan of Lily Allen's 'The Fear' so I'd be keen to get her producer Greg Kurstin."
