In tonight's episode, the Casa Amor twist continued as Callum - currently coupled up with Shaughna Phillips - shared a bed with new girl Molly Smith.
He was seen putting aftershave on but insisted: “Sharing a bed doesn’t mean anything. If you’re not cuddling them or spooning them.”
But Mike warned: “FYI Shaughna – she will get p****d off.”
In a preview for the next episode, Callum was seen snogging Molly after telling her: "I always said it would take me someone special for my head to turn."
Meanwhile, an unaware Shaughna said in the main villa: "I just don't know what I will do if he comes back with a girl. I would not be able to live in this villa."
In Tuesday's episode, Molly tried to find out what Callum’s thinking with Natalia Zoppa helping by starting a round of quick-fire questions.
When she asked if Callum would kiss Molly that evening, he was left speechless.
Later, he spoke his thoughts through with Finn.
Finn asked: “What are you thinking mate? Your head is a little bit more scrambled than it was yesterday.”
Callum replied: “Absolutely.
“I just think you can’t help how you feel. This is a test at the end of the day. It’s not like you do it out of spite.”
Finn said: “If you’re feeling Shaughna you do the best thing for that. If you’re feeling Molly, you do the best thing for that. I don’t think you’ve got to worry. I bet you didn’t expect it?”
Callum adds: “Every time she walks past I’m just like…”
Finn asked: “Do you have that with Shaughna?”
Will Callum take Molly back to the main villa? The Casa Amor twist continues all this week on Love Island.
