On this day in 1994, in the borough of the Bronx, in the city of New York, a baby named Saoirse Una Ronan was born, and the world of acting would never be the same. 

Happy birthday, Saoirse Ronan! Ireland's favorite leading lady turns 24 today.

At a time when most people are really digging in to figure out their careers and adult selves, Ronan, the star of films like Brooklyn, Lady Bird, and The Lovely Bones, has already been nominated for three Academy Awards, won a Golden Globe, and we couldn't be more proud of her. 

In honor of her birthday, here are five facts you must know about Saoirse Ronan. 

She pronounces her name "SUR-sha"

Despite her fame, most interviewers devote plenty of time to how unusual her name is and the correct way to pronounce it. Saoirse, which means "freedom" or "liberty" in Irish, has traditionally been pronounced "SEER-shə," but Ronan has her own pronunciation: "Saoirse like 'inertia'".

Ronan was born in the Bronx, New York, to Paul and Monica Ronan, making her a dual citizen of the US and Ireland. She has been open about the value she places on this, as well as her parents' initial undocumented status.

"My mum was a nanny, and she was adamant that she was going to have me there so I wouldn’t ever have to go through the tough time that they had in order to get their visas," she said in a 2015 interview with The Telegraph. "I’m blessed in that I can just move to New York or LA if I want. Even when it comes to work, I don’t have to worry about visas. So thanks, Mum!" The family moved back to Ireland when Ronan was three years old. 

She was nominated for her first Oscar at age 13

Ronan's major breakout role as Briony Tallis in the film adaptation of Ian McEwan's novel Atonement also earned Ronan her first Academy Award nomination for Best Supporting Actress. She was the 13th youngest actor ever nominated for one of the major categories. 

Now, just 11 years later, she's been twice nominated for Best Actress - for her starring roles in the film adaptation of Colm Toibin's Brooklyn and Greta Gerwig's Lady Bird.  

She once helped give Ed Sheeran a tattoo - and spelled it wrong on purpose

Ronan starred in the eagerly anticipated music video for Sheeran's song Galway Girl, and of course they had the craic while filming it. Part of the experience was Sheeran getting a tattoo of the song title in Ronan's handwriting, but she brilliantly decided it would be way more funny spelled "Galway Grill." Despite initially acting like he was caught unawares, Ronan set the record straight that it was all intentional.

Her best friend is her Brooklyn co-star Eileen O'Higgins

When Ronan won her Golden Globe for Best Actress in a musical or comedy earlier this year for Lady Bird, she began her acceptance speech by saying: "I just want to say how inspirational it is to be in this room tonight. I'm here with my best friend, Eileen..." 

Naturally, everyone was curious about who Eileen was and how she was lucky enough to be Ronan's BFF. As it turns out, Eileen is Eileen O'Higgins, who acted alongside Ronan in Brooklyn, as her friend Nancy.

It wasn't the first time Ronan gave Eileen a shout-out - she also noted in numerous interviews that Eileen was the first person she called when she found out she was nominated for an Oscar for Brooklyn. Best friends share and support! 

Happy birthday, Saoirse!
