Rita Ora has said she learned a lot from working with Iggy Azalea on their new single, and Kill Bill themed video, Black Widow.

The 23-year-old Never Let You Down singer told Capital FM, "Iggy is just so involved in her videos. She really is involved. So I learned a lot from that.

"She got inspiration from old Korean ninja things and Kill Bill and then I got inspired by the leather catsuits. I watched Kill Bill like three times. I learned a lot and we just had fun."

Ora added that there was never an air of competition between the two stars, "It was so nice to have no competition vibes. We have so many different ambitions but we work well together, really well."
