London, Dec 3 : Singer Robbie Williams was offered 20 pounds for showing his bottom for a bet on a TV show -- and the pop star gladly accepted.

However, this isn't the first time for him - he had bared his derriere in the past on a TV show for 10 pounds when his band "Take That" was in its prime, thesun. co. uk reports.

The band is now in Scandinavia promoting their album "Progress".(IANS)
