The Jonas Brothers were all smiles as they kicked off a whirlwind visit to the UK this morning.

The three brothers, who are in the country to promote new film Jonas Brothers: The 3D Concert Experience, gave a brief interview on GMTV.

The trio said they were big fans of the UK during their chat with presenters Kate Garraway and Ben Shepherd.

And Kevin revealed he would be working in a café if he wasn't a singer.

The Jonas Brothers will greet fans in London's Leicester Square tomorrow for the UK premiere of their rockumentary.

The film goes on general release on May 29 for two weeks – so make sure you don't miss it.
