Kristen Stewart is getting more open about her love life than ever before.

The 26-year-old actress has been showing plenty of PDA around Los Angeles with her former personal assistant, Alicia Cargile, and in a new interview with Elle UK, she refers to Cargile as her girlfriend for the first time.

"I think also right now I'm just really in love with my girlfriend," Stewart says bluntly when asked about Cargile. "We've broken up a couple of times and gotten back together, and this time I was like, 'Finally, I can feel again.'"

Stewart explains why she's been much more candid about her relationship recently, and although she doesn't mention her ex-boyfriend by name, seems to recall her difficult previous experience dating her "Twilight" co-star, Robert Pattinson.

"When I was dating a guy I was hiding everything that I did because everything personal felt like it was immediately trivialized, so I didn't like it," she shares. "We were turned into these characters and placed into this ridiculous comic book, and I was like, 'That's mine. You're making my relationship something that it's not.' I didn't like that."

"But then it changed when I started dating a girl," she continues. "I was like, 'Actually, to hide this provides the implication that I'm not down with it or I'm ashamed of it,' so I had to alter how I approached being in public. It opened my life up and I'm so much happier."

Indeed, Stewart and Cargile looked pretty smitten with one another on Sunday, when they were snapped holding hands after having a sushi date in Los Feliz, California.

"They were both in a good mood, smiling, and very animated towards each other," an eyewitness told ET. "When standing outside their car, Alicia started hugging Kristen and kissing her on the neck. They were both aware that they were being shot, but were not shying away from the camera."

The couple was also spotted kissing earlier this month while out for coffee in Los Angeles.

Stewart and Cargile appeared to have rekindled their relationship in May -- when they were spotted holding hands during the Cannes Film Festival -- following reports that Stewart split from French singer Stephanie Sokolinski that same month. Stewart and Cargile have been linked as far back as April 2015, when they were snapped holding hands in Los Angeles.

"I've discovered a way to live my life and not feel like I'm hiding at all," Stewart recently told The Los Angeles Times about the speculation surrounding her personal relationships. "And I think that's pretty apparent for anyone who cares -- not that everyone does. But I think that if you had been tracking it in any way, it's more apparent that I'm more relaxed than I used to be."
