JLS were spotted arriving at the Radio 1 Studios ahead of an interview with Nick Grimshaw.

As expected, the boys were mobbed by a group of their teenage fans as they made their way into the building in West London to chat with new breakfast show host Grimshaw, no doubt to promote their latest single 'Hottest Girl In The World' and their new album.

The boys have a busy few months ahead especially with the news that the singers will be hosting a special show on Sky 1 at Christmas.

Celebrating four years of success, Marvin Humes, Oritse Williams, Aston Merrygold and JB Gill will create a winter-wonderland for 400 of their lucky fans.

The festive show - titled A Very JLS Christmas - will be 90 minutes long and will see the boys sing classic festive carols as well as their own hits.

Check out the snaps of the boys outside Radio 1 below...
