Saoirse Ronan has revealed how the American accent she adopts in most of her movies has become almost second nature to her.
The Carlow actress was speaking on The Ellen DeGeneres Show, where the host made her scream twice with her famous scare pranks.
Little Women actress Saoirse said she finds it really easy to adopt the US accent.
"It's something I've just always done," she said, adding that her favourite accent is the drawling California Valley girl voice famously adopted by the Kardashian sisters.
"I do it all the time," she said. "What I love about it is you don't have to push your voice at all. You just sort of chill and talk at the same time."
She also told DeGeneres that she found it much easier to drive in Ireland than on Californian highways.
"I'm driving now. I had a provisional licence for a few years so I had to have a fully licensed driver beside me," she said.
"A provisional Irish driver's licence is like half your licence, so it's like, 'We don't fully trust you yet, so put your mam or dad in your car at all times'.
"Basically, it just stops you driving your car because all you want to do is drive on your own.
"I did it this year around my birthday and I got it.
"I'm a terrific driver. I haven't driven in LA yet because driving in LA scares me.
"At home we have literally four cars on the road at any given time whereas here you have four lanes of traffic.
"It's just a lot. I don't know why I drive, actually."
The 25-year-old, who is already getting Oscar buzz for her Little Women role, said she lives between London and Ireland when not in Los Angeles.
