Oh, how we love looking at pictures of drunk celebrities (mainly as it makes us feel less like winos ourselves.) The latest casualties are Girls Aloud who were out this weekend at the Burlington Club in London's Mayfair, celebrating Kimberley's little sister Amy's 21st birthday. Winners of the Pissheads of The Night award goes jointly to Nicola and Sarah, who in true tabloid star style, gave each other a "look, we're lesbians, honest" drunk snog for the waiting paps. Notably absent was Nadine – AGAIN *raises eyebrows*
