Jennifer was seen getting Casey to down shots of vodka, but after he winced as the alcohol burned his throat, Jennifer mocked him saying: "You don't drink like a man".
Marnie then suggested they go to the pool, but not before Casey ranted to the camera in private: "This Jen girl is doing my head in.
"She keeps calling me a p**** and now I'm drinking vodka which I don't even like.
"I'm trying not to be a kill joy but I'm just not having fun, I wish it was just me and Marnie here."

As the gang headed out to the pool, Casey told Marnie to jump in, and the Geordie Shore wasted no time pulling down her bright pink swimsuit and exposing her breasts.
Looking over her shoulder, she said "Ooh la la" before kicking the rest off – just a day after her former co-star Charlotte Crosby shared a Snapchat clip of herself naked.
As Jennifer joined her in a bikini, Marnie took a run and jump into the water, flashing her bottom at the camera as she did so.
Talking to the camera afterwards, Marnie said: "I'm having so much fun.

"Jen is hot and I'm not going to lie, it's clearly making Casey jealous and I'm buzzing about it, win-win."
After Casey refused Jen's invite into the pool, she jumped in alongside Marnie and the girls had a whale of a time splashing around together.

Jen then issued another insult to Casey, accusing him of being gay for drinking wine and not getting in the pool with them.
He then walked off back inside before declaring: "I have had it with this girl, she's f***ing me off now."
