Tinie Tempah is rumoured to have agreed to help X Factor judge Tulisa Contostavlos pick her three finalists, according to reports.

The star will be joining N-Dubz beauty Tulisa as a mentor on the show, says The Sun.

A source told The Sun: "Tulisa knows Tinie really well and would love for him to join her with the contestants once they are through bootcamp."

They added: "She originally planned for her N-Dubz bandmates Dappy and Fazer to join her but the show producers thought that was a gamble. Gary is also close to Tinie and has been working with him on the new Children In Need single.

"He knows the show is huge and realised it would be great for his profile. He has a few things to wriggle out of, but is determined to be involved."

Meanwhile, Kelly Rowland is rumoured to have asked Usher to help her pick her three finalists.

An insider told The Sun: "He loves the show as he's been on it a few times and gets on well with Simon Cowell and the top brass,"

They explained: "Plus, he knows a thing or two about finding new talent as he was the man who discovered Justin Bieber. It's fair to say Bieber has done pretty well for himself since."
