Justin Timberlake is set to duet with Leona Lewis.

The two pop superstars plan to collaborate for a cover of Whitney Houston's 1992 worldwide hit single "I Will Always Love You" - originally penned by Dolly Parton.

A source told Britain's The Sun newspaper: "They will record the track in the next few months and are just waiting for a period when they're both free to go into the studio.

"Leona and Justin are huge fans of each other's music and are raring to go."

"SexyBack" singer Justin has previously admitted how desperate he is to work with the British star after they met at his concert "Justin and Friends" last year.

He said: "I'm going to go pimp myself to Leona Lewis, because I think she's an amazing singer."

Meanwhile, Leona has been banned from touring by her manager Simon Cowell - who discovered her on UK TV talent show "The X Factor" - because she is too "shy".

A source said: "Although Simon believes in Leona as a world-class solo singer, he still feels she does not have enough confidence to play to large crowds on her own.

"Leona is Simon's little baby and he is very aware of how shy she is."
