Girls Aloud star Kimberley Walsh was blown away when she watched her band mate and friend Cheryl Cole singing on last weekend’s X Factor.

All of Girls Aloud (except Nadine Coyle, who says she wasn’t invited) went to the show to offer their support for the judge, and Walsh was impressed by the performance.

Writing in her OK! column this week, Kimberley said: “Sarah, Nicola and I went to see The X Factor to see Cheryl perform her new single, Promise This – she was amazing!

“I always get nervous for any of the girls if they’re doing solo stuff as we’re used to being there for each other – but I needn’t have worried as she was fantastic.

“Afterwards, we all crammed into Cheryl’s dressing room and had a few glasses of wine. Cheryl’s at The X Factor so much at this time of year that it’s the perfect place to catch up without any paparazzi about.”
