There are few things rowdier than a group of girlfriends let loose in Las Vegas for a naughty weekend away.
Some of the Girls Aloud have jetted to Sin City to help Cheryl Cole celebrate her 29th birthday in style.
Nicola Roberts has kept fans up to date on the girls' activities, from the moment she and Kimberley Walsh settled into their Upper Class cabin, to downing shots of tequila with the birthday girl.

The entire group enjoyed a meal together at an upmarket restaurant in the party town on Saturday, Cheryl's birthday.
Attendees donned masks bearing the singer's face, and their table was decorated with balloons for the occasion.
Nicola tweeted a picture of the group, who kept their identities shrouded behind the masks.

Cheryl had earlier written on her own Twitter page, 'Erm… few questions!! Who am I Where am I Why am I What am I'
could be forgiven for feeling a little bewildered, given that she was
spotted drinking shots of Patron tequila the evening before.
Roberts posted a picture of herself, Cheryl and Kimberley downing the drinks, captioning the picture simply 'PATRON'.

Despite the premium liquor, the trio had looks of disgust on their faces as they attempted to down them in one.
The girls were partying at XS nightclub, where will.i.am was playing a DJ set. Cheryl slipped behind the decks to dance while the Black Eyed Peas singer gave her a shout out.
Earlier in the day, Nicola tweeted a picture of Kimberley enjoying a cocktail in first class. It is unknown if Nicola indulged, after staying up all night so she didn't miss her flight when her filming schedule ran until 5.30am.
