BFFs like Cheryl Cole and Kimberley Walsh are meant to tell each other EVERYTHING.
So we can understand that Chezza was a tad miffed when Girls Aloud bandmate Kimbers failed to fill her in on the details of her brand new single.
The 'Strictly Come Dancing' star releases her debut solo track 'One Day I'll Fly Away' on Monday.
But it seems like brunette Geordie Cheryl Cole is the last to know.
She tweeted and posted on her Facebook page last night: "Me: i still dont know your album release date ?! Kimberley : oh it's out Monday babe ! Me: r u for f real. Were U just gonna keep that to yourself!! K: no I've been doing promo for weeks ! Me: u told the magazines before me. Wow K: oh... Me: nice!"
Cheryl was clearing only joking with her BFF but we can't really blame Kimbers for struggling to get around to sharing her dates with her best mates, she has after all been non-stop since getting back together with Girls Aloud at the of last year, making the Strictly final AND working on this solo album.
The 31-year-old says that she's focusing on introducing songs of the world of musical theatre to a younger generation, rather than being focused on chart notoriety.
She explained to S Magazine: "The idea is to turn some of the songs on their head
and bring something different to them, and also I want to introduce them
to the younger generation - you know, our fans and people who wouldn't
usually buy a musicals album."
Meanwhile Kimberley told OK! Magazine that she, Cheryl Cole and and Nicola Roberts are the biggest gossips of the girlband - and get on Sarah Harding and Nadine Coyle's nerves.
She said: "Probably me, Cheryl and Nicola [are the biggest gossips]. The other two look at us like we’re old women."
