"I am completely and utterly single," she told the Daily Mail.
"Never in a million years would I go on Love Island if I was in a relationship, and I'm sure if I had a boyfriend, he wouldn't be very happy with it either.
“We ended quite dramatically at the start of March,” she said of her relationship with Aaron, “but then we made friends, and we share a dog, it's a shared dog and he's been looking after it.
“It was at my mum's house and my mum couldn't look after three dogs, so it seemed right, he was looking after it. We broke up quite a while ago now, but the ship has definitely sailed between him and me.
“He had no idea I was going on Love Island, and it was a shock to him. Apparently, he drove me to the airport, which is a complete and utter lie, I got a taxi.
"Hopefully, he's moved on and I definitely have. It was a funny rumour!”
Aaron plays for Premier League club Brighton & Hove Albion, as well as the Republic of Ireland national team. He is currently on loan to Venezia.
