The Casa Amor star shared a snap on Instagram of her on a night out ‘cheersing’ with a glass of wine.
It was posted after Casey and Claudia were pictured together on a “double date” with Tom Clare and Samie Elishi.
While Rosie failed to comment specifically on her ex, she pouted in the snap that was uploaded in the early hours of the morning.
Despite going their separate ways while on this year’s Love Island, rumours are beginning to swirl of a romantic reunion between Casey and Claudia.
On Saturday night the pair headed out as a four, with Casey, 26, putting his arm around Claudia, 28, as they posed for a snap.
Claudia looked a vision in a black blazer dress and heels, and she wore her blonde locks down.
Meanwhile, Casey cut a more casual look in a blue top and white trousers as he headed to Musu in Manchester with the group.
The pair looked very cosy as they joined their pals Samie and Tom, who are in a relationship after meeting on the hit ITV2 show.
Samie previously explained: “We love Casey and Claudia – we love them seperately but we love them together as well.
“Claudia was my best friend in there and Casey was yours – it just all made sense.
“Casey messed it all up.”
Claudia and Casey ended their romance after Casey fell for Love Island bombshell Rosie.
But last week Casey and Rosie called it quits – leaving the door open for a possible reunion for recruitment consultant Casey and boutique business owner Claudia.
Rosie and Casey were the first coupled up casualty of the latest series of Love Island.
Casey confirmed the news on Instagram during a Q&A with fans.
One follower asked: “How are things with you and Rosie?”
Casey replied: “Rosie and I have spoken… she’s such a great girl.
“Life outside the villa is just very different and we will remain friends moving forward!”
