According to the Daily Star, the singer was due to release her next single 'Everybody, Everyone' featuring Dizzee Rascal but has cancelled the plans to concentrate on cracking the US.

A source told the paper: "She has been working non-stop promoting the album since recovering from malaria and she needs a break."

"She told her record label she didn't want to heavily promote 'Everybody, Everyone' so the release has been scrapped over fears it would be a flop."

Meanwhile, Cheryl Cole has confirmed that she has spoken to Rihanna about recording a duet.
