BFFs Jordin Sparks and Leona Lewis

The two singers, who became stars by winning their respective reality shows, have developed a friendship during the past few months.

Sparks told the Daily Star, "I met Leona right after she won X Factor. We were recording in the same studio in the States."

Jordin explained, "It was cool because we both understood what the other one was going through." She added, "I haven’t seen her for a couple of months but maybe we could do something together one day. There are a lot of people I’d love to work with and she’d be one."

Sparks recently hit the charts with her duet with Chris Brown, No Air.
