You may think unlikely pairing, but actually we're not surprised these two are friends. After all, Casey is close pals with Richard's BFF and co-star Ollie Locke so it's probably not unusual for her to be in the company of him!
Casey first met Ollie while living with him in the Celebrity Big Brother house. The pair starred on the reality show's thirteenth series along with Lee Ryan, Sam Faiers and eventual winner Jim Davidson.
Taking to Instagram earlier today, Casey shared a few snaps from her recent getaway. One photo was of herself and Richard (who returned to Made In Chelsea alongside Ollie last year) shopping for fruit.
Casey told her fans: "@richarddinan helping my buy some melons!!! #frenchmarkets #wheninfrance #melonbuying."
She also shared another picture of the pair enjoying dinner with friends and told her followers she'd had the "best time" on her hols. Ollie, meanwhile, was nowhere to be seen and hadn't appeared to have joined Casey and Richard on their sunshine break.
Well, it was a pretty last minute trip. Taking to Twitter earlier this week, Casey tweeted: "So I literally just booked a flight, packed my bags and got to the airport in 2hours #spontaneous #byebyeEngland #HelloSouthOfFrance."
The lucky thing!
She then followed that up with a tweet, revealing she had arrived safely and gushing about her pals. She said: "Arrived in south of France to a beautiful villa and a glass of rose vino! I ❤️ my friends @KatHounsome @RichardDinan and Mr Brocket."
And as you can guess, Casey has been turning us green with envy with her holiday snaps ever since...
