London, Jan 12 : Pop star Leona Lewis and Justin Timberlake will soon be teaming up to belt out a duet, penned by Dolly Parton.

Leona and Timberlake, who have a mutual admiration for each other, are delighted to breath fresh life into Dolly's ballad.

"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," the Sun quoted a source, as saying.

On the other hand, Leona's mentor Simon Cowell feels that although she has the talent for singing a duet, she does not have the capability to thrill millions of fans on tours.

"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," a source said.

However, others feel that Leona should be given the freedom to experiment and fully grow as an artist. (ANI)
