Ariana Grande has apologised for her bizarre behaviour at a doughnut shop in July

The 22-year-old singer caused controversy when she licked a number of the bakery items which were on display and also said she hated America but Ariana has now admitted her actions were offensive.

Speaking on 'Good Morning America', she said: "First of all, my behaviour was very offensive and I apologised. There's no excuse, or there's nothing to justify it. I think as human beings, we all say and do things that we don't mean at all sometimes.
