Is Kristen Stewart a lesbian? Twilight star seen wearing boys' underwear and holding hands with Alicia Cargile

American actress Kristen Stewart has sparked rumours that she is lesbian, and is dating best friend Alicia Cargile.

In images published by the Daily Mail, the 24-year-old Twilight star is seen wearing boys' underwear and holding hands with Cargile, a Los Angeles-based visual effects producer, while vacationing in Honolulu, Hawaii.

As the photos circulated online, Stewart's fans reacted on Twitter.

Stewart has been single since going after a high-profile breakup in 2012 with co-star Robert Pattinson.

Stewart and British director Rupert Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in the Hollywood hills.

Following that, Robert Pattinson ended his four-year relationship with the Still Aliceactress.

However, the 28-year-old Remember Me actor moved on from Stewart and is now dating FKA twigs.

During an interview with Vanity Fair France, the On the Road star talked about some vulnerabilities she faced while growing up.

"I was kind of a cocky kid, and so when you go to school and you're not fully accepted as this girl who was supposed to look like a girl, it affected me. I would get called a man—and all this stuff. There was a very, very brief time when it bothered me. Then it ended because when I started working," she said.

"I never tried to shape people's perspectives of me, which is something that a lot of people do. There are certain actors and artists who want to be a certain kind of actor or certain kind of artist, and I'm really not like that."

"I try not to let it mess with me, because my true personal life, as much as people think they know about it, they don't know d*ck sh*t. Who could?" Stewart went on.

"By the way nobody knows. Nobody knows what the f*ck is going on. You're going to die. You're going to lay next to the people that you know the most in life, the people that you're going to grow old with. But you're going to lay next to them in the middle of the night deeply curious about them and who they are, because nobody f*cking knows anything," the actress said.
