It's been six long years since Christina Aguilera last released an album, but she's on the comeback trail with 'Liberation', her eighth studio album that's due for release on June 15th.

The pop star has made the first single from the album, 'Accelerate', available online and to say that it's divided opinion is understating the case just a smidge.

The track - which was produced by Kanye West, FYI - features Ty Dolla $ign and 2 Chainz and has a definite Rihanna vibe to our ears - which isn't going down well with some people. 

Others, on the other hand, think it's the best thing she's done.
