Rita Ora's rapper boyfriend Ricky Hil has vowed never to duet with his lover as it would risk wrecking their romance.

The R.I.P hitmaker began dating fashion designer Tommy Hilfiger's son earlier this year (14) following her split from DJ Calvin Harris.

During their relationship, Ora and Harris worked on the track I Will Never Let You Down together, but the pop star will not be repeating the collaboration with her new man.

Hil tells Britain's Daily Mirror newspaper, "Rita and I listen to each other's music and tell each other what we think, but I'd never work with her... I think that always ends relationships. It's the same with designing, you've got to do your own thing and support each other when you can."
