In a recent interview with Harper's Bazaar U.K., the 53-year-old actress opens up about her love life following her 2014 split with Tim Burton, whom she shares two children, 16-year-old Billy and 11-year-old Nell.
"You break up, you grieve, you get bored of grieving, and then you finally move on," she says of her and Burton's breakup after 13 years together. "I’m very happy with someone else. It’s been a bit of unexpected magic in my life."
Bonham Carter also reveals that she and Holmboe, a 32-year-old Norwegian writer, share a "fur baby," Pablo the Tibetan terrier.
"Mother and dog are doing very well," quips Bonham Carter -- who, according to the article was "vocal in her irritation that paparazzi shots of her with her new partner... recently appeared in the papers."
In addition to happiness in her personal life, Bonham Carter is also experiencing joy in her professional endeavors, thanks in large part to her upcoming role of Princess Margaret in season three of The Crown.
"When I turned 50, I worried it was downhill all the way, but it’s quite the opposite," she says. "I don’t think I’ve ever been happier or more fulfilled."
"This huge blooming of television means character-driven stories, so there’s a lot of choice and a lot of work," she continues. "When I was young, you were considered 'older' over 30."
In order to prepare for her role as the princess -- who Bonham Carter met on several occasions before her 2002 death -- the actress met with many who had been close to Margaret and even enlisted the help of a psychic.
"It sounds ridiculous," she admits. "I know most people will be like, 'Oh God, she really is mad,' but I definitely feel there are energies and people who stick around."
Bonham Carter previously opened up about her visit to a psychic at the Cheltenham Literature Festival earlier this month.
"She said, apparently, she was glad it was me. My main thing when you play someone who is real, you kind of want their blessing because you have a responsibility," Carter said, via The Guardian. "So I asked her: ‘Are you OK with me playing you?’ and she said: ‘You’re better than the other actress’… that they were thinking of. They will not admit who it was. It was me and somebody else."
"That made me think maybe she is here, because that is a classic Margaret thing to say. She was really good at complimenting you and putting you down at the same time," she continued. "Then she said: 'But you’re going to have to brush up and be more groomed and neater.' Then she said: 'Get the smoking right. I smoked in a very particular way. Remember that -- this is a big note -- the cigarette holder was as much a weapon for expression as it was for smoking.'"
Season three of The Crown drops Nov. 17 on Netflix.
