Jason Derulo's hits 'What If', 'Ridin Solo', 'Whatcha Say' and 'In My Head' have topped the charts, and he's fast becoming the hottest R&B star around. The multi-talented 20-year-old dances, acts, writes his own material and has already worked with Rihanna, Leona Lewis and Rick Ross to name but a few.

Derulo will be signing albums at 6pm on Thursday, but only 250 admittance wristbands will be given out. These will be distributed at 4.30pm on Wednesday. Only one wristband can be collected each, so pick up in person to ensure you're not left outside HMV, ridin' solo (sorry, had to be said.)
