JLS on stage at GAYJLS' Marvin Humes on-stage at G-A-YJLS mania just hit a new peak.

But that's no surprise when the boys have taken to ripping their own clothes off on-stage.

The British boyband hit the stage to perform for the crowd at G-A-Y at London club Heaven.

During the sweaty routine the lads stripped off to reveal their exceptionally toned torsos.

The band stormed to the top of the charts this week, stealing the number one spot from Cheryl Cole, with their second single Everybody In Love.

It's been less than twelve months since JLS came second to Alexandra Burke on last year's X Factor, but it hasn't stopped their meteoric rise to fame.

As well as winning two prestigious Mobo awards earlier this year, Aston Merrygold, Marvin Humes, Oritse Williams and Jonathan "JB" Gill are now being followed everywhere by hordes of screaming teenage girls.JLS JLS have already had two number 1 singles

Their appearance to turn on the Christmas lights at Manchester's Trafford Centre last week saw thousands of screaming fans swamp the shopping centre.

But their huge popularity means the boys have been warned to watch their step.

And that means no more signing fans' body parts.

Oritse told the Daily Mirror: "Girls were pushing their boobs in our faces and asking us to sign them.

"But then there was a girl in America who sued after she had an autograph written on her in pen which caused an allergic reaction.

"Now we have to be so careful."
