Pugh made the news public in an interview with Harper's Bazaar where she discussed the public furore over their relationship which had a 21-year age gap.
The Little Women star said: “We’ve been trying to do this separation without the world knowing, because it’s been a relationship that everybody has an opinion on."
She added about her breakup with the former Scrubs actor: “We just felt something like this would really do us the benefit of not having millions of people telling us how happy they are that we’re not together. So we’ve done that."
Pugh's relationship with Braff was the subject of much tabloid speculation since they began dating in 2019.
She did previously address the age difference in an interview last year saying: "I'm 24 and I can't choose who I love … There's a reason why I'm not with someone my age—It hasn't worked. So who are you trying to match me up with?"
Pugh and Braff originally met on the set of In the Time It Takes to Get There, a short film directed by the Garden State star.
Pugh is also set to star in Braff's upcoming directorial effort A Good Person alongside Morgan Freeman and Molly Shannon.
Pugh was nominated for an Oscar for her performance in Little Women and has also received acclaim for her roles in films such as Lady Macbeth, The Falling and The Little Drummer Girl.
She also recently joined the Marvel Cinematic Universe as Yelena Belova in Black Widow and Hawkeye.
