Actress Emily Blunt says she still stutters around her family.
The Devil Wears Prada star - who developed the speech impediment at the age of seven - rarely struggles to speak in front of strangers.
However, she admitted she sometimes has problems getting her words out in front of family and friends.
Blunt - who is married to The Office star John Krasinski - said: "Weirdly enough, I stutter less with a person I'm unfamiliar with. And then with my family or my husband it'll come out more which is strange."
Although her episodes of struggling to speak are now rare, Blunt admitted she had a tough time with her stutter when she was growing up.
"As a child and early teen I didn't speak as much - because I couldn't.
"Maybe that was a good thing because I soaked it all up like a sponge. But I don't remember it as a conscious thing. I think I just wanted not to talk. Too embarrassing."
