Speaking to Harper’s Bazaar, the British actor explained that she tired of mourning the highly publicised relationship and has now happily moved on.
“You break up, you grieve, you get bored of grieving, and then you finally move on,” Bonham Carter told the publication.
“I’m very happy with someone else. It’s been a bit of unexpected magic in my life.”
The actor has previously been notoriously private about her personal life.
In 2015, Bonham Carter told Red magazine that she “could write a thesis” describing what happened between her and Burton, who famously lived in separate adjoining homes.
“It is all-absorbing when a relationship breaks down, but I think we’re coming through it, and I think we’ll have something very precious still,” she continued.
“Our relationship was always somewhat special, and I think it’ll always remain special.”
Elsewhere in the new interview, Bonham Carter discusses ageing, recalling turning 50 three years ago and thinking “it was downhill all the way”.
“But it’s quite the opposite,” she added. “I don’t think I’ve ever been happier or more fulfilled.”
The actor stars in the latest series of The Crown, in which she plays Princess Margaret.
“This huge blooming of television means character-driven stories, so there’s a lot of choice and a lot of work,” she continued. “When I was young, you were considered ‘older’ over 30.”
