Rita Ora teams up with boyfriend Calvin Harris for new track

Pop star couple Rita Ora and Calvin Harris are making sweet music together - they've headed into the studio to work on a collaboration.

The Hot Right Now singer and her superstar DJ beau penned her new single, Will Never Let You Down, together, and they were stuck side-by-side during the recording of the track.

Announcing the duet on BBC Radio 1, Ora explained, "Honestly, it was so natural. I wouldn't have done it if it didn't make any sense. I was never really against (working with) people I'm involved with (and) doing something personally.

"We were sitting at home, he started humming and then I started humming and then we hummed together!"

The pair bounced back from recent reports they had split up by walking the red carpet hand-in-hand at the Grammy Awards last Sunday (26Jan14).
