Cheryl hit the milestone yesterday (30 June) and was snapped cuddling up to the trio in nightclub Hakkasan - but it appears the excitement all got too much!
Cheryl, Kimberley and Nicola - who fans have dubbed 'Chimola' - were looking rather glam, with the birthday girl opting to wear a stunning sleeveless white dress and a simple pair of skyscraper heels. Tre, meanwhile, went for a particularly dapper look for his lady's big night and wore a tux to her party.
But as they sat in a line with their arms draped around each other, it appeared as though they were ready to turn in for the night!
Kimberley shared the funny picture with her Twitter followers in the early hours of today, saying: "24hrs later #vegasbaby."
Meanwhile, Nicola also uploaded a picture taken at the party, which showed herself cuddled up to Cheryl and Kimberley. Alongside it she wrote: "#JuStLoVe."
Throughout the day, Cheryl had been inundated with birthday wishes from fans so logged on to thank them all.
She said: "Awwww!!! Thank you all sooo much for my birthday wishes, you are the sweetest!!!!!!"
