By the seventh Harry Potter film you'd expect all the actors to be pretty confident when they're on the set.
But Emma Watson and Rupert Grint have both said they're feeling nervous about filming a certain scene in Harry Potter and the Deathly Hallows.
That's because their characters, Hermione and Ron, end up sharing some pretty romantic scenes in the movie.
Both Emma and Rupert have admitted they're feeling nervous about having to kiss for the cameras.
Emma, 18, told the Daily Telegraph newspaper that she'd never had to kiss anyone on screen before.
The Harry Potter stars have grown up a lot since the first film!
"Of course I am nervous about it, but apparently it gets quite boring after a couple of takes, that's what Daniel [Radcliffe] said to me anyway," she said.
And last month 20-year-old Rupert told the same newspaper that he was dreading the scenes.
"As I've known Emma for so long, I reckon it will be 10 times worse," he said.
