And she reveals all to best pal Camilla Thurlow the next day.
After her night with Alex, Montana spills: “We got to Base Two. Well, the Love Island Base Two.”
“What’s a Love Island Base Two?” Camilla asks.
“A continental boob grab,” Montana explains, “It was more like a boob tickle so that was nice. He’s very affectionate which normally makes me feel nauseous. Am I punching?”
“No! Montana, anyone with you is punching and I’ll buy the hat for the wedding,” Camilla tells her.
Meanwhile, in the Beach Hut, Alex opens up about his feelings for Montana: “Montana is great She ticks the boxes. I do feel like a puppy with a new owner. I’m excited but I don’t want to show it so much but I can’t stop looking at her, for me she is the whole thing.”
It's not just Montana who's smitten, with Camilla revealing her feelings for new guy Craig.
She tells the beach hut: “In terms of potentially having a romantic relationship with someone, I could never in a million years could have expected to be as lucky, to feel the feelings that I’ve felt in the last 24 hours with Craig, so it’s been lovely, absolutely lovely, I couldn’t be happier.”
Love Island 2017 airs tonight at 9PM on ITV2.
