Record chiefs have told Blue to shape up. They have told the band they are getting fat and fear that their extravagant lifestyles could eventually leave them unattractive to fans.

Lee, Duncan, Antony and Simon are all regular showbiz partygoers, prompting execs at their label Innocent to draft in a personal trainer.

The lads made a dramatic entrance at Sunday’s Party In The Park as they were hoisted onto the stage on wires.

The trainer will enforce a strict regime of healthy eating and daily exercise on the boys. A close friend of the band told the papers “Blue are supposed to be heartthrobs but their management were worried fans will lose interest if they turn chubby. Plus, their bosses reckoned all those booze sessions and late nights were beginning to take their toll” added the source.

As you would’ve probably heard already, Blue are not the first boyband to face enforced physical regimes in order to be thin.Westlife recently spent a portion of a million pounds to be thin, especially Bryan McFadden who apparently has been training to be skinny after Simon Cowell told him he was too fat.

In other Blue-related news, Blue is facing legal action from another band labeled as Blue, which claims that the name-based confusion is ruining its recording career.

Members of the lesser-known Scottish band Blue, made up of Hugh Nicholson and Ian MacMillan, along with their record company The Record Label, have launched a High Court action against the London-based Blue as well as their recording label, Virgin Records and parent company EMI Records.

The action seeks to prevent London-based Blue from using the name Blue for the purpose of records and recording. It also claims damages from the members of the band for using the name previously.

Hugh and Ian formed the Scottish Blue in the 1970s and it’s said the band still records.
