The CBB gang, who formed a close bond on this year's series, met up at Jim Davidson's wife Michelle's birthday party and it looks like they had a blast catching up together.
It appears the party was held at the Davidsons' house and the foursome posed for a picture while relaxing on the sofa.
Jim looks like he is in hysterics in the snap, while Ollie seems rather stunned and Casey is smiling. Dappy, meanwhile, is pulling his best gangster pose!
Sharing the picture with fans on Twitter, Dappy said: "@JimDOfficial @ollielocke and @CaseyBatchelor nice 2 see all of u again last night..."
Ollie, who has just returned from a holiday in Italy, was looking forward to catching up with his pals. Ahead of the party, he tweeted: "Such a crazy day running around London.. Perfect week ahead and it's tonight it's a bit of a reunion.. Without cameras!!"
The CBB stars weren't the only famous faces at the party, as former EastEnders legend Barbara Windsor made an appearance too - and Casey couldn't get enough!
Grabbing the actress for a selfie, which she then shared on Twitter, Casey gushed: "I finally met my idol ...... The legend that is Miss Barbara Windsor. Amazing lady xxx."
Aww, sounds like Casey is Babs' number one fan!
