LILY ALLEN was forced to make an embarrassing confession live on radio this week - after admitting she once sent a nude snap of herself to a fellow celeb

The singer forced out an awkward apology to fellow singer RICKY WILSON - after mistakenly sending the KAISER CHIEFS frontman a nude photograph of herself.

The Smile singer intended to send a saucy text message to an unknown male companion - but inadvertently sent the picture to Wilson.

She tells British radio DJ Chris Moyles, "That was really embarrassing. I was completely topless."

Allen declined to name who the picture was supposed to be sent to, but joked:

"It was meant for Rick Astley."
