London (ANI): After making headlines with her platinum blonde look, singer Lily Allen once again hogged the limelight with swish new bob cut and a see through dress which flashed her undies. The 'Smile" singer stepped out with ex-Seb Chew in a blue see-through dress revealing her underwear - to join the guests including David Walliams at a house party in West London, reports The Sun.

The 23-year-old crooner"s dinner date on Monday, where she stepped out in a platinum blonde wig and transparent hippy-style spaghetti-strap top, has sparked rumours of reunion with her ex-flame as she is said to be desperate to have a new man in her life.
