Diana Vickers is planning to release a range of underwear called Diana Vickers' Knickers.

The 18-year-old singer - who rose to fame through UK TV talent show 'X Factor' - is currently in negotiations with several companies about putting her name to the branded pants.

A source told BANG Showbiz: "We are planning to launch an underwear range - Diana Vickers' Knickers - soon. We are just trying to work out who with."

Diana recently unveiled a sexy new image in the video for her debut single 'Once' - in which she is seen singing in a multitude of outfits, including nothing but a white shirt and a saucy short sequined dress.

She has also revealed that Gary Lightbody from Snow Patrol had given her the song 'Just Say Yes' for her album - but took it back to use for his band because it was too good.

After coming fourth on 'The X Factor' in 2008, Diana took the lead role in West End production 'Little Voice' - for which she won London Newcomer of the Year at the Theatregoers Choice Awards.
