Kristen Stewart has opened up about her relationship with girlfriend Alicia Cargile saying she is "really in love".

The former Twilight actress, whose high-profile relationship and break-up with co-star Robert Pattinson was tabloid fodder for many years, says she is enjoying being much more open with her current relationship.

In a cover interview with Elle UK, the 26-year-old actress said: "When I was dating a guy I was hiding everything that I did because everything personal felt like it was immediately trivialised, so I didn't like it.

"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."

The American actress, who is starring in Woody Allen's new film Café Society, revealed that things have changed since she started dating Cargile, a visual effects producer.

"But then it changed when I started dating a girl", she explained. "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.

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