Girls Aloud singer Kimberley Walsh collapsed in a London nightclub after her drink was spiked with a date rape drug, according to bandmate Sarah Harding.

The singer hit headlines last month (Mar07) when she was photographed being carried, apparently intoxicated, from showbiz nightspot Embassy by her singer boyfriend Justin Scott.
