Rupert Grint has revealed that his kiss with Harry Potter co-star Emma Watson was a bit tricky.

But the 22-year-old actor said that despite some initial awkwardness, the smooch ended up feeling quite natural.

Speaking to The Sunday Times, Grint explained, 'The kiss happened quite naturally. It was quite a tricky kiss, a bit strange, but quite sweet really,' he said. 'It was just one shot, but we had about six takes. It was all right, yeah. Easy after the first take.'

He also admitted that he wasn't prepared for how upsetting the end of the franchise would be.

'It felt like the last day at school, packing up all the stuff in my dressing room, all the old toys still there from when I was 11. I'd underestimated how emotional it would be. We all cried,' he said.
