The trio headed out to London's Zuma restaurant for a slap up meal as Kimberley enjoyed a break from 'Strictly' training, but their other two bandmates were nowhere to be seen.
The girls went hell for leather as they dolled up for Kimberley's do - Chez in a mustard coloured leather dress, Kim in a jumper and leather trousers and Nic donning a jumper and a leather skirt.
Cheryl tweeted during the evening: "Almost ate myself to death with the girls @KimberleyJWalsh @NicolaRoberts why did we do the desserts ???"
Kimberley replied: "Asking myself the same question! Time to undo the leather trousers I think..."
Nicola added: "I can't even think about it! I feel sick! Help me pls! X."
Meanwhile it is looking like Girls Aloud will not top the charts with comeback single 'Something New'.
Midweek indications reveal that Olly Murs is currently at number one with his single 'Trouble Maker', ahead of the girls by 28,000 copies.
Their final chart position will be announced on Sunday.
