Singer Rita Ora still can't believe Jay Z is her boss as she isn't "comfortable" with the idea of working with the successful rap mogul.

She feels lucky that she gets to work alongside the rapper-producer, who signed her to his music label Roc Nation in 2009, but admits she often finds it overwhelming, reports femalefirst.co.uk.

The 23-year-old said: "I still can't believe Jay Z is my boss, it never sits comfortably with me."

Ora, who is dating Scottish DJ Calvin Harris, is also excited for her fans to hear her new music.

She said: "I've done a song with Prince, it's going to be on the new album. Prince is a genius. Me and Calvin have worked together on a few tracks, he's so talented."
