However, the 'Blame' star admitted that his tunes weren't picked for the eventual cut.

"She listens to everything - I know that - but she's got a strong idea and identity and an idea of what her album should sound like."
He continued: "It's not like they put me on 'We Found Love' because I'm signed to Roc, they did it because it's a f**king good song. But it's OK because I'm working on my stuff and it's going fine so I'm not concerned about it."
