Gemma has been avidly watching this year's series of CBB and admitted last night that she has the hots for model Calum.
Taking to Instagram, the Only Way Is Essex star shared a picture of Calum laying in bed. She then told her followers: "I am seriously in love with Calum Best, he's gorge, @calumbest." Oo-err!
But while Gemma may have set her sights on Calum, it seems she might have some competition...
Towards the end of last night's CBB, Calum was shown in the kitchen getting pretty close to US model Cami Li. It's fair to say the pair were flirting, although both admitted to having a 'special person' in their lives.
While she giggled and fawned over Calum, he warned Cami that she has a "boyfriend".
However, confusing viewers by attempting to have a cryptic chat, she referred to the unknown man as her "sister".
"I don't have a boyfriend, I have a sister - and you have a brother," Cami told Calum.
"Well, yes," he replied. "There's someone who, when you come in here, you think about more. You think to yourself, 'Oooh'. I'm a single dude, but I'm allowed to have somebody who is on my mind."
Smiling, he then told Cami: "Dude, you've got a boyfriend - remember that. Whatever you want to call it!" She replied: "I don't like it that you have a brother. You're mine, no one else's."
Err..ok! Could there be a new CBB romance on the cards, or will Cami and Calum's 'siblings' put paid to any sparks between them?
Only time will tell!
