I'm The One DJ Khaled feat. Justin Bieber
We're already smitten with Christina's new single in much the same way as a raver is to their glowsticks. It's a full-on dancefloor tune, with a video that sees Ms Aguilera return to her old raunchy ways...it's dirrty and it's fab!
The single will be followed by the worldwide release of her eagerly-awaited fourth studio album 'Bionic' on June 8th.
