But much to viewer’s dismay, Calum has so far rejected the advances of flirtatious Cami, who has made it quite clear she has feelings for the footballer’s son.
And now the reason for Calum’s shyness has become clear - as his secret girlfriend has come forward.
Ianthe Rose Cochran-Stack, 23, who is also a model has allegedly been dating Calum since last year, but the pair have been keeping things quiet.
A source told The Sun: ‘It’s no surprise he brushed Cami off. Why go for a burger when you have steak at home?’
Ouch. Poor Cami.
According to the same source, Ianthe ‘isn’t bothered’ by the flirting between Calum and Cami going on in the house - and was pleased to see Cal reject the model in bed last week.
And it seems Ianthe was proud of her man for resisting temptation, posting to her Instagram page: ‘Nothing is sexier than a man or a woman who can face temptation and have the level of maturity to say “this isn’t worth losing what I have.”’
Is this the woman who has finally turned Calum Best?
