Onerepublic frontman Ryan Tedder has offered to pen tracks for R and B superstar Rhianna - after labelling the Umbrella star the next Britney Spears.

The Apologise singer, who has wrote smash hits for Natasha Bedingfield and Leona Lewis, is sure he can work his musical magic for the Bajan beauty after she declared her admiration for his work in an elevator.

He says, "She (Rihanna) actually approcached me in an elevator in New York about a month or two ago and she was like, 'I'm such a fan of your music,' and I said exactly the same thing, so we were like, 'Well let's do something.'"

"I'm gonna try and deliver a couple of hits. She's the new Britney Spears."
