Cheryl Cole gets a little grumpy with best friend Kimberley Walsh
Chezza noticed a message on her Girls Aloud band mate's Twitter page that told her followers she was taking time off from her role in Shrek The Musical in April - and was surprised she didn't know about it.
'Erm. Where r you going from the 16th-22nd of April and why do I not know about it already.. #imallears *foldsarmstapsfoot*,' quipped Cheryl, 28, in a Tweet.
Best friend Kimberley quickly replied to explain that she was off to see her sister - and that she hadn't forgotten about her.
'Ha ha Sal's doing a play in Sweden so I'm gonna visit her! Our holiday is gonna be when I finish *smiling* #loveourgirliehols,' Tweeted Kimberley, 30.
