Kristen Stewart would never be accused of being an open book, but she’s been more candid than ever about who she is and what she thinks on her promo tour for her upcoming movie “American Ultra.” Could it be a sign of maturity?

Stewart seems more sure of herself than ever, especially after winning the prestigious French Cesar Award in April for her role in 2014 drama “Clouds of Sils Maria.”

At 25, she has to be happy about where she is in her acting career and it shows in her latest film, “American Ultra,” with Jesse Eisenberg. It’s a dark comedic romp.

It’s also a major departure from her appearance in a string of serious films like “Clouds,” “Camp X-Ray,” “Still Alice” and “On the Road.”

If she was intent on proving herself as an actress, she’s largely succeeded earning critics’ respect–something she never received for her role in the blockbuster “Twilight” series.

In “American Ultra,” she plays Phoebe Larson, the stoner girlfriend of Eisenberg’s character, Mike Howell, a convenience store clerk who doubles as a deadly sleeper agent.

When he’s inadvertently activated, he’s targeted for elimination by government assassins. But taking him out is no easy task. Both were psyched about playing action roles.

“I love getting physical” Kristen said on the “Today show” this week. “I wish I got to do a little more fighting. I have like 30 seconds in which I prove myself. My elbows prove to be useful.”

On the tour, Stewart has also touched on her personal life, including rumors that her personal assistant, Alicia Cargile doubles as her lover.

When asked by Nylon magazine if she wanted to make any “pronouncements about her sexuality,” she replied with both candor and ambiguity.

“Google me, I’m not hiding,” she said. (So she is gay?)

Then added:

“I live in the f*cking ambiguity of this life and I love it. I don’t feel like it would be true for me to be like, ‘I’m coming out!’ No, I do a job. Until I decide that I’m starting a foundation, or that I have some perspective or opinion that other people should be receiving… I don’t. I’m just a kid making movies. If you feel like you really want to define yourself, and you have the ability to articulate those parameters and that in itself defines you, then do it. But I am an actress, man.”

So she’s not gay?

In a few years, Stewart believes it won’t really matter. But that’s as far as she goes on her personal relationships, including ex Robert Pattinson. “That’s not something I would ever talk to the f*cking public about; that’s crazy,” she said.

Stewart also talked about the cat and mouse game she plays with the paparazzi who constantly dog her.

“It’s like I’m involved in a weekly comic book. I have this assigned personality… which I helped create, I suppose. People stand to make a lot of money on people like me — it’s this booming industry, so why would you go and change the character that people are paying for?”

During an appearance on “The Tonight Show with Jimmy Fallon,” the talk show host chided her for always being photographed scowling.

In fact, she says she smiles a lot, not always with positive results.

“I went out yesterday and wanted to be able to take a walk around New York without being followed by paparazzi, so I went out and was just like ‘ha ha ha ha!’ The next day it totally ruined my chances because they said, ‘Ooh we made so much money on those smiling photos,’ and now there’s like 50 [paparazzi] outside.”
