Calum was all smiles yesterday as he shared several selfies with fans, telling them that he and Ianthe were boarding a plane to Abu Dhabi.
The couple looked to be in a joyous mood as they pulled several facial expressions while on board.
And it seems like celebrations for the pair started early, as former Made In Chelsea star Ianthe was seen clutching a glass of champagne in her hand.
Calum finished in third place in the last series of CBB, but it was only after his stint in the house did he reveal he pretended to be single to land a spot on the show.
Calum did, however, hint at his secret romance in cryptic conversations with housemate Cami Li.
Speaking about pretending to be single, Calum told The Sun last month: "Going on the show, I was conscious like a few others that I wanted to be 'single'.
"Celebrity Big Brother wouldn't touch me for years and I've worked hard for this chance - so I wasn't going to jeopardise it by saying I was taken."
Following his stint, Calum has revealed that he is releasing a memoir about his life growing up with his footballer dad, George Best.
