An X Factor fan exclusion zone will be set up around Margate Winter Gardens to keep the venue clear of youngsters desperate to catch a glimpse of boy band sensation JLS before their sell-out concerts.

Anyone spotted hanging around the clifftop venue hoping to see their idols during Friday and Saturday will be moved on.

Security is tight for the two shows that will bring thousands of youngsters to theatre for the two high-energy shows.

Paul Palmer, entertainments and families manager, said: "Unless you have a ticket for the shows, please do not turn up on the evening. We already have a long list of those who don't have tickets but are waiting and hoping for any possible returns. There will be none spare at the box office for anyone else.

"Doors to the venue will be manned all day Friday and Saturday. Police will control the area outside the venue and a professional security team will handle interior security.

"We're concerned for the safety of young fans who may have it in mind to hang around out the front of the venue in Fort Hill or at the rear on the clifftop promenade. They will be moved on if they turn up.

"We're not being killjoys, simply seeking to ensure safety for ticket holders."

It is understood that JLS - who have taken the pop charts by storm with singles Beat Again and Everybody In Love - will not be staying overnight in the area between the two gigs.
