Leona Lewis is set to team up with Justin Timberlake to record a cover of Dolly Parton's I Will Always Love You.

The X Factor winner is reportedly joining forces with the SexyBack star to sing the 1974 song, famously covered by Whitney Houston in 1992.

They are both said to be waiting for some free time in their busy schedules so they can book some studio time together.

A source told 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."

Meanwhile, it was also revealed that Lewis is also working with producer Timbaland on her second album.
