According to friends of the ‘reformed’ playboy, Calum already has his eye on American model Cami Li.
A source told the MailOnline: “Calum likes a naughty girl and Cami Li has a bit of a twinkle in her eye. He liked her straight away.
“He loves girls who have tattoos, particularly on the ankle and foot - and of course, she is a tattooed glamour model so he's in his element.
“He's dated girls who look just like her in the past and I could tell the moment he set eyes on her in the house that he was hooked because he has a certain look about him when he likes someone.”
It’s not just Cami that Calum has been eyeing up. According to his friend he had already checked out the credentials of Ex On The Beach star Chloe Goodman before entering the Celebrity Big Brother house.
They said: “He knew she was rumoured to be going in and he told me he thinks she's a lovely looking girl and really sweet.”
Calum has dated scores of women, including Hollywood star Lindsay Lohan and glamour model Bianca Gascoigne.
He awkwardly also briefly dated fellow housemate Alicia Douvall.
We can’t wait to see if sparks fly between Calum and any of his female housemates!
