Former X Factor judge Cheryl Cole has proved that she knows how to have a good time by taking a group of her BFFs on a boozy trip to Las Vegas to celebrate her 29th birthday.

Cheryl flew manager Will.i.am and Girls Aloud band mates Nicola Roberts and Kimberley Walsh first class to Sin City, and before they even landed, half the partygoers were squiffy thanks to the free on board cocktails.

Nicola provided a running commentary of the celebrations via Twitter, and tweeted a shot of the party sitting down to dinner at an upmarket eatery in Vegas yesterday.

The Mail on Sunday reports, “Attendees donned masks bearing the singer’s face, and their table was decorated with balloons for the occasion…”

And it seems a good time and a lot of alcohol – mostly Patron Tequila – was had by Cheryl, who tweeted, “Erm… few questions!! Who am I? Where am I?? Why am I?? What am I?”

She also tweeted her thanks to fans who’d contributed donations to her foundation, saying, “I can not believed you have raised over £2000 for my Foundation !! That is sooo special to me!

“You are so kind thoughtful and generous.”

Of her charity, whose website you can go to by clicking here, Cheryl states that her mission in establishing the foundation is to “try and help young people all over the UK and put money raised through my Foundation into projects like the one’s that The Prince’s Trust already runs.

“Projects which make it possible to believe in yourself again, learn new skills, build confidence and eventually get a job and make a new start.”
