Pop star Lily Allen made sure fans didn't get a bum deal at a recent gig in London - by mooning stunned revellers halfway through her set.
The British singer was in high spirits after her latest single The Fear shot to the top of the U.K. charts.
And the feisty star was keen to celebrate her success with fans at the British capital's G-A-Y night spot on Saturday (31Jan09) night - by cheekily exposing her rear.
Allen donned a a skimpy blue negligee and stockings to open her show, before slipping into a sexy air hostess uniform to cover Britney Spears' Womanizer track - just like the one the pop superstar wore in her famous Toxic promo.
And the risque routine certainly paid off.
A fan tells Britain's The Sun newspaper, Shes got a great figure with curves in all the right places. She looked absolutely fantastic.
Allen scored her second British number one on Sunday (01Feb09), knocking U.S. dance sensation Lady GaGa from the poll position.
