And although she loved catching up with her TOWIE faves, the Celebrity Big Brother star did find things a little awkward!
Tweeting from behind-the-scenes during yesterday's episode, she said: "Well I'm in the studio watching #TOWIE with the cast!!! Well the tension in the air........awkward!!!!! Eeekkk! #tenners."
We can only imagine!
Kicking off the fourteenth series, viewers saw the girls head to Tenerife - or Tener-grief as Lydia Bright renamed it. While Ferne McCann and Danielle Armstrong came to blows, Leah Wright and Chloe Sims clashed over Elliott Wright.
Back home in Essex, Chloe and Elliott then crossed words as tensions rose about their former relationship. Their confrontation left Elliott disappointed with his ex, with the reality star saying he thinks Chloe has been "totally disrespectful" towards him.
Following the episode, Casey joined the TOWIE cast and Mark Wright for spinoff show TOWIE: All Back To Essex.
Giving her thoughts on the series' opener, the former model said: "I think it was the most dramatic show I've ever seen. There was just argument after argument. There was awkward tension in that room [during the show] like you wouldn't believe... My favourite part though has got to be Bobby's one-liners!"
And making sure to catch-up with Bobby [Norris] while she was there, Casey couldn't resist grabbing a selfie with him!
Sharing her photo to Instagram, Casey told her followers: "Loving this boy @bobbycnorris."
Cosying up with Bobs, Casey also managed to grab a quick a snap with Gemma Collins too. Although, she didn't quite manage to squeeze into the TOWIE cast's 'Oscars selfie'.
Maybe next time, eh?!
