The rumours are true: Beyoncé is to join Coldplay during their Superbowl halftime show next month, it has been revealed.

It's no huge surprise, considering the pop star features on Chris Martin and co.'s new album 'A Head Full of Dreams' - but whether she will reprise her vocals from that allbum or join them for something completely different has yet to be revealed.

Either way, she'll be at the Levi's Stadium in Santa Clara, California on February 7th to inject a bit of much-needed glamour into the affair.

Entertainment Tonight also report that Bruno Mars will guest with the band, while Rihanna is also rumoured for an appearance.
