Lily Allen bares her butt to her fans

London (ANI): British singer-songwriter Lily Allen has once again topped the charts with her new single 'The Fear', and she celebrated it by flashing her butt to her fans.

Allen, 23, was wearing an electric blue Little Bo Peep costume and stockings, a frilly top, lacy knickers and matching blue stockings with towering beige platform heels. As she sang at London's G-A-Y club from her new album 'It's Not Me, It's You', she cheekily bared her bottom to the audience.

"She's got a great figure with curves in all the right places. She looked absolutely fantastic," the Sun quoted Simon Roberts, 27, a fan of hers, as saying. The 'Smile' singer was later seen partying with her brother Alfie, 22, and his girlfriend Jaime Winstone, 23.
