R&B star Ne-Yo has urged Britney Spears to get in touch with him, so she can record the two songs he's been holding especially for her.

After confessing that he and the Toxic singer had fallen out over tracks he wrote for Spears' comeback album and then allowed Pussycat Dolls star Nicole Scherzinger to record them, the So Sick hitmaker revealed the two songs the pop superstar really liked are still hers if she wants them.

Ne-Yo claimed he wrote six to eight tracks for Spears, but offered two of them to Scherzinger when she asked the songwriter for tunes for her debut solo album.

He says, "There were two songs that Britney really, really liked and I told them that I would set those two songs aside and nobody would hear them until Britney Spears' voice was on them.

"This was a few months ago and I haven't heard anything from them since."

Meanwhile, rapper 50 Cent has blamed Kevin Federline for the predicament Spears currently finds herself in.

The hip-hop superstar believes Spears would still be enjoying her phenomenally successful pop career had she never met her now-former husband Federline.

And 50 Cent thinks Spears' public collapse - including wayward behaviour such as shaving her head before a recent rehab stint - wouldn't have happened had Britney avoided her dancer-rapper ex.

He says, "I think she brought too many people in. Kevin whatever-his-name-is, who is he? She made him a star.

"She should have left his ass in the closet, then he would have stayed and everything would have been exactly the way it needed to be." - Wenn
