"Who's got theirs??? I'm just leaving the house and already can't wait to get in so i can blast it #proud," Cole tweeted to her fans.

Cole recently joked about not knowing when Walsh would be releasing her solo album, by recounting a conversation between themselves.

Meanwhile, Girls Aloud will start their reunion tour of the UK later this month, beginning in Newcastle on February 21.

The girl group have reportedly banned alcohol from being consumed backstage during the jaunt, to ensure Sarah Harding does not falter in her recovery from alcoholism.
