Rupert Grint "can't remember anything" about when he had to kiss Emma Watson.
The pair had to lock lips for a scene in Harry Potter and the Deathly Hallows: Part 2 as their on-screen alter egos Ron Weasley and Hermione Granger.
But Rupert has revealed filming the smooch was so disturbing that he has done his best to block it out of his mind.
He admitted: "I never look back at that scene. I've known Emma since she was literally 9 years old and we had this very brother-sister relationship.
"And it just felt very surreal. I have a memory of her face getting closer and closer. Like, 'Oh my God.' I can't really remember anything apart from that."
Rupert was speaking to People magazine as he attended the Celebration of Harry Potter event at Universal Orlando theme park.
But it seems he wasn't the only one to have those feelings about the kissing scene.
Emma previously said that snogging Rupert "felt like incest".
She laughed: "It was the most horrible thing I've ever had to do ... it just felt like incest. That's the only way I can describe it.
"It was fine that I was actually kissing him because I had my eyes closed so I could not think about the fact that it was him. The worst bit is when we had to open our eyes and look at each other because then I was just like, [laughter] and then we couldn't keep going. But we did it in the end. Six takes - not bad. It could be worse."
