The Celebrity Big Brother housemate confirmed today he'd separated from Made In Chelsea's Ianthe-Rose, saying: "Sadly we have had to go our separate ways."
It's thought Calum and Ianthe-Rose were together around nine months.
In a statement to The Sun, model and reality star Calum said he wished his ex-partner nothing but the best for the future, adding: "I sincerely hope we remain friends. She is the first girl I really loved and I cherish the time we spent together."
Calum and Ianthe-Rose had looked blissfully happy together back in March when they enjoyed a sunsoaked holiday together to Abu Dhabi. They also went to Tuscany the following month.
Since appearing in CBB earlier this year, Calum has gone on to release an autobiography called Second Best: My Dad and Me, which details his relationship with his late father, footballer George Best.
