This morning on 98FM's Big Breakfast, we caught up with the sister of this year's Love Island winner Greg O'Shea.

Last night Greg and Amber won Love Island and his older sister Laura told us she couldn't be any prouder.

Laura revealed her little brother didn't tell her he was entering the Villa, "I only found out when he went in.. Mom knew and two of his closed friends knew, but I didn't!"

Greg became a favourite in the Villa when he arrived two weeks ago and swept Amber off her feet with his Irish charm.

Laura reckons he definitely stayed true to himself and that's why everyone loved him: "The moment he walked in, he was just himself and I thought, thank god!"
