Singer Lily Allen ended up flashing her derriere while leaving a popular haunt here, even as she flaunted a glowing tan in a thigh-skimming dress which had a print of a semi-naked woman on it.

She perked up the look with a fierce plaited up hairdo with streaks of pink and a pair of bright pink trainers.

Allen, a mother of two, also sported a grin while unaware that she was accidentally flashing a bit of her bottoms to paparazzi.
