Yellowstone fans are losing their minds over Beth Dutton star Kelly Reilly’s real-life accent

Yellowstone fans have been left in shock by Kelly Reilly’s real accent, with many admitting they had ‘no idea’ she was British.

The 47-year-old actress has been starring as Kevin Costner’s daughter Beth Dutton in the Paramount Network western since its 2018 premiere, and during that time has worked tirelessly with a dialect coach to perfect her Montana twang.

On Thursday, Kelly appeared on The Drew Barrymore Show, where she surprised the 49-year-old host and the audience with her natural speaking voice.

“I never thought you had an accent!” Drew exclaimed.

“Well, that’s thanks to my dialect coach, because she’s amazing, Jessica Drake,” Kelly replied.

‘We were actually going for a Montana accent, but that’s her [Beth] trained. She comes from a very, very wealthy farming family. I wasn’t going to say, “Hi, ma’am.”

“It wasn’t for me.”

“But I definitely wanted to get that Montana dialect right,” Kelly continued. “So I worked with Jessica.

“I’d worked with her on Flight and True Detective and all those other American accents I’d done.

“But for Beth it was more about the voice because she smokes a little bit. She drinks a lot of bourbon.”

“She has a grater,” Drew noted.

“Like a guttural noise.”

“I listened to Kevin a lot because he really deepened his voice for John Dutton, so I just stole it. I just copied it,” Kelly added.

Like Drew, viewers at home were completely surprised by Kelly’s normal accent.

In response to a clip from the show posted on the official TikTok page, one person said: “My brain is fighting her voice/accent… it just doesn’t register that she doesn’t naturally speak like Beth.”

Another wrote: ‘I didn’t know she was English.’

Echoing a similar sentiment, someone else responded: “I thought she was American all the time. Wow, she can’t do that. I love Beth.’

‘MY BRAIN WON’T FIT!’ shouted a fourth.

A fifth added: “I would never know she was British.”

Kelly has captivated audiences playing the only daughter of Kevin Costner’s character Beth.

Born and raised in Chessington, London, Kelly attended Tolworth Girls’ School in Kingston, where she studied drama for GCSE under the watchful eye of her mother, hospital receptionist, and police officer father.

Before discovering her talent for acting, she enjoyed working with horses and thought she would have a future in equestrian sports.

The actress first appeared on TV in 1995 and began her career in the BBC Children’s drama series The Biz alongside former EastEnders star Paul Nicholls.

She also landed a role in 1995’s Prime Suspect 4: Inner Circle after getting her foot in the door by writing to the drama series’ producers.

In addition to her roles on television, Kelly managed to build a name for herself in the theater world, working with Terry Johnson in four productions: Elton John’s Glasses (1997), The London Cuckolds (1998), The Graduate (2000) and Piano/Forte ( 2006).

At the age of 26, Kelly received a Laurence Olivier Theater Award nomination in 2004, making her the youngest actor to receive such an honor after starring in After Miss Julie, a Michael Grandage production at the Donmar Warehouse in London’s West End in 2003.

She next played the role of Caroline Bingley in 2005’s Pride And Prejudice alongside Keira Knightley.

Her first leading role came in the 2008 horror film Eden Lake, in which she co-starred with Hollywood heavyweight Michael Fassbender as a young couple terrorized by a group of murderous teenagers during a weekend getaway, earning her a Best Actress nomination at the British Independent Film Awards.

The following year, Kelly kept her star profile alive with a role in the British primetime series Above Suspicion, playing a rookie detective determined to prove herself in the male-dominated police department.

Hollywood soon beckoned to Kelly, who starred in both 2009’s Sherlock Holmes and the 2011 sequel A Game of Shadows, in which she played Mary Watson.
