Leona Lewis is "really grateful" for the collaborations on her second album.

The British singer - who shot to fame in 2006 as the winner of the third series of the British television series, the 'X Factor' - said she's very happy to have worked with some talented artists on her new album 'Breathe', but was surprised she didn't fancy Justin Timberlake, her childhood heartthrob.

She said: "I mean, when I was younger, yes, I thought he was because he was in a boyband, but now, not really! I am more in awe of his talent. I am just so glad that I got to do this album with such amazing people. There's a duet with OneRepublic on there and I worked with Max Martin, so I feel really grateful that I was able to work with them."

The 24-year-old star said Justin was very easy to work with because he was so "focused and chilled", just like her.

She said: "He's cool. We're good working together because we both know what we want to achieve. But I still get star struck and stuff."

Leona admitted she isn't quite so keen on getting into acting like her childhood pin-up however.

She told new! magazine: "I don't know, it depends. If it's the right kind of thing, I think I would be up for it."
