Had a bit too much to drink? Cheryl looked tired as she headed home after an eventful evening
She's had a difficult few months after being fired from the X Factor USA and trying to re-establish her reputation.
So Cheryl Cole can definitely be forgiven for letting her hair down on a rare night out with manager will.i.am.
The 28-year-old singer looked slightly worse for wear in a picture she posted on her Twitter page which showed her clutching a bottle of champagne and holding her finger up in a rude gesture to the camera.
Cheryl expressed her regret over the photograph and her drunken antics by tweeting this morning: '
I just walked past the mirror and caught a glimpse of someone.. I have no idea who she is..'
How rude! Cheryl later posted this picture of herself sticking her finger up to the camera
She then added: 'That's it.. Me and alcohol are not friends..', before continuing: 'Too many bubbles :('
The Girls Aloud star was later seen heading home after an eventful evening, struggling to keep her eyes open as she sat in the back of her car with friends.
Earlier in the evening, Cheryl had looked polished as she posed for photographers at the HTC and Beats Audio party at London's Roundhouse.

The Promise This singer went for an edgier look for her evening out, teaming a pair of skintight leather trousers and an unusual face-print top.
Cheryl accessorised her look with pointed black court shoes, lashings of red lipstick and teased her hair into waves to complete her new image.
She had earlier posted a picture of herself at the event, with the caption: 'I'll be rocking them BEATS! Yup yup yup yup!'
The words are from the Black Eyed Peas track Boom Boom Pow.
And Cheryl wasn't the only star to share pictures of the occasion on Twitter as will.i.am, who headlined the event, later tweeted followers to a shot of the pair posing up together.
Friends: Will.i.am, who is Cheryl Cole's manager, tweeted this photo of him backstage with the axed X Factor judge, referring to her as 'Little Miss Tweety Bird'
