Kristen Stewart has reflected on her "young and stupid" romance with former Twilight co-star Robert Pattinson.
The Spencer star, 31, looked back on making the blockbuster vampire romance franchise, telling The New Yorker about the moment she laid eyes on Pattinson.
"It was so clear who worked," Stewart told the magazine of doing chemistry tests with potential actors to play Edward to her Bella.
She added that Pattinson, now 35, had an "intellectual approach that was combined with 'I don't give a f*** about this, but I'm going to make this sing.'"
"I was, like, 'Ugh, same.' And, whatever, we were young and stupid and, not to say that we made it so much better, but that's what it needed, and that's what anybody playing those parts needed to feel," she added.
Stewart also said that Twilight director Catherine Hardwicke was "kind of the perfect person to do a young-adult novel that had these dark romantic elements.
She had this childlike openness and teenage triggers, and her whole sensibility was that the movie was going to feel horny and overconfident." Hardwicke told the magazine why she felt Stewart was the right fit for the movie series, which also starred Taylor Lautner in the lead love triangle.
"She's Bella. She's got to be Bella, because she keeps it so grounded and so real. I built the whole film around her," the filmmaker said of Stewart.
The pair famously dated after meeting on the set of Twilight and seemed to be going strong until photos emerged of her kissing her married Snow White and the Huntsman director Rupert Sanders while she was dating Pattinson.
The couple reconciled shortly after but ultimately called it quits in 2013.
Earlier this month, Stewart announced her engagement to girlfriend Dylan Meyer after two years together.
Screenwriter Meyer popped the all-important question to the Twilight star, who broke news of their engagement during an appearance on SiriusXM's The Howard Stern Show.
While promoting her upcoming movie Spencer - in which Stewart portrays Princess Diana - she couldn't help but gush over the proposal.
"We're marrying, we're totally gonna do it," she said. "I wanted to be proposed to, so I think I very distinctly carved out what I wanted and she nailed it. We're marrying, it's happening."
The actress has previously dated supermodel Stella Maxwell, Sara Dinkin, St Vincent, Alicia Cargile, Rupert Sanders, Michael Angarano, and the late Anton Yelchin.
