Lily Allen accidentally sent a topless photo of herself to Kaiser Chiefs frontman Ricky Wilson.

"The Fear" singer confessed she mistakenly sent the saucy text message to the rocker while she was on holiday.

During Lily's interview with BBC Radio 1 DJ Chris Moyles on January 19, Chris told her: "Ricky goes to me, 'I got this weird text the other day from Lily Allen of her topless.

'And I'm looking at it going why has she sent me that? Literally a minute later, 'beep beep... Sorry, wrong Ricky!' '"

The 23-year-old singer - who has provided backing vocals for Ricky's band - admitted there had been a mix up and went on to joke it was intended for "Never Gonna Give You Up" singer Rick Astley.

She said: "That was really embarrassing. I was completely topless. It was meant for Rick Astley!"

Lily is no stranger to being captured topless on camera.

Last week, the star - who has often been photographed baring her breasts during sun-drenched holidays - revealed her "third nipple" to a Dutch TV chat show host, saying: "It gets hard when you touch it."
