Lily Allen reportedly spent her Valentine's Day on a sixteen hour bender with pals. The singing starlet, who has recently been battling with a relationship break down and a miscarriage, was spied ripping up London town with close friends Kelly Osbourne, Kimberly Stuart, Alex Chung and Peaches Geldof. Lily's day started just before noon, as she attended the Fall 2008 Luella Bartley show at the Claridge's Hotel. In honor of the designer she arrived wearing a Luella Bartley dress and sunglasses. Kelly Osbourne also attended the show, and it looked like the pair jointly decided to wear eccentric shades of lipstick, as Lily pouted in purple, and Kelly revved it up in red. Afterwards the gang headed to Vivienne Westwood's London Fashion Week show, before heading to the Hadley Freeman book launch in Mulberry on Bond Street. But, the antics didn't stop there. With energy still left, Lily and friends continued on to the Dolce club for an after party. The in true celebrity style, they made the final stop of night at night club Punk, where Miss Allen was spotted leaving at 2:45am. Not a bad effort I say! Pictures by Splash News / Elizabeth Lippman
