Robert Pattinson’s “I Don’t Know” is one of the most revealing interviews to date. During this candid chat with Billboard, the Twilight movie star opens up about her sexuality, her controversial relationship with actress Kristen Stewart, and much more.

The English actor was previously married to FKA Twigs before dating the Snow White and the Huntsman director; now, he’s dating singer Katy Perry. So, it’s no wonder that he’s been talking about his love life a lot lately.

“I don’t know if she’s bisexual or not,” Pattinson said of his longtime girlfriend Stewart. “I think it’s something she’s explored in the past but I don’t know that about her current self. I think she’s an independent woman and that’s something I really admire about her.”

The 35-year-old entertainer also discussed his attraction to older women, why he signed on to play a transgender parent in Netflix’s upcoming movie, Ryke. . .

On His Attraction To Older Women:

Pattinson said that he finds “beauty in all ages” but noted that he’s had a “crush” on actress Helen Mirren. The Twilight actor has admitted that he feels “very protective” of Stewart and that he can see “a lot of [Mirren]’s charm” in Stewarts. He continued, “She’s very kind and funny. In some ways, she’s very similar to my mother.”

While it’s flattering that Pattinson would cite similarities to his mother, the English actor also said that he finds older women more desirable than younger ones. In fact, he was recently in a relationship with French model Estelle Lefebvre, whose real name is Eleanor. Pattinson said that he likes “being with older women because they have more experience.”

“They’ve been through so much, you know?” he added. “They know how to treat a man right.”

On Playing A Transgender Parent:

Pattinson said that he was initially hesitant to get involved with the project because of its sensitive subject matter, but he ultimately decided to take on the role after reading the script and meeting with director Jeff Nichols. The British actor revealed that he was inspired to play the transgender role after watching celebrities’ efforts to have their children blessed by LGBTQ leaders and activists during the royal wedding last year.

The “Fathers 4 Justice,” an organization that fights for the “equal rights of fathers,” held a special event during the wedding of Prince Harry and Meghan Markle. The group asked LGBTQ celebrities to speak with Harry and to advocate for “equal parenting rights,” according to Variety. Pattinson said that he appreciated that the organization focused on “equal rights for everyone” but that he wishes they had also championed for his character’s right to be with the woman he loves.

“It just so happens that I’m dating a woman who is also a part of this community,” Pattinson said. “I think it’s really great that they’re trying to change the narrative around trans men and women and show that there’s a place for us. I love my girlfriend but, at the same time, I also really want to be with Ellen [Stewart]. I don’t know if that’s possible. I don’t know anything anymore.”

Pattinson also discussed how he wants to be treated as an actor, how he approaches his work, and if he has any advice for young hopefuls.

On If He Followed His Mother’s Advice On Men:

The English actor said that he didn’t necessarily follow his mother’s advice when it came to men. However, he did agree that the older a woman is, the more attractive she is. “I think she [his mother] always said that men grow out of love, which I know is true,” he said. “But growing out of love doesn’t mean you don’t care anymore. Or maybe it does but I think it takes a very experienced woman to know how to make a man happy.”

On What He Wants From A Relationship:

The Twilight actor said that he wants “someone to share my life with,” but he’s also open to the idea of having “fun” with a woman. Pattinson also said that he doesn’t want to “ruin” a relationship by getting too serious. “I don’t want to put pressure on anyone,” he said. “I just want to see where things go.”

On If He Has Any Advice For Future Actors:

Pattinson said that he doesn’t necessarily have advice for future actors but that he does believe there’s “a lot of room” for growth as an actor. He also said that he has “no idea” what his next move is after the end of the Twilight series.

The English actor concluded by saying that he’s “not going to lie” and that there are many facets to his character but that he hopes people will focus on the “positivity” that he brings to the roles he takes on.

On His Upcoming Projects:

Pattinson said that he hasn’t quite figured out what his next move is after the end of Twilight but that he does have some ideas. He also said that he’ll be taking on “very dark” roles in the near future.

On What He Enjoys About Coming Back To Los Angeles:

The Twilight actor said that he enjoys coming back to Los Angeles because he has a lot of friends and family there. He also admitted that it’s “great” to be able to explore different parts of the country while filming. However, he said that he still enjoys being in England and Australia because the “weather is always beautiful.”

On If He Will Be Reclaiming The “Dark” Identities He Played In The Twilight Series:

Pattinson said that he doesn’t necessarily plan on reclaiming the “dark” identities he played in Twilight. However, he did say that he’s not going to shy away from “intense or dark” roles. He’s also not going to avoid taking on political issues either. Pattinson said that he wants to stay “true to [himself]” and that he doesn’t want to be “limited” by any sort of identity.

On Having Fun With Women:

Pattinson said that he doesn’t see any reason why he can’t have fun with women. While he has been married twice, his first wife, FKA Twigs, is now his manager. So, she could potentially chaperone any potential relationship that he has. The English actor also said that he’s open to the idea of marrying the right woman.

“I think the most important thing is just to be happy and comfortable in your own skin,” he said. “For me, it’s definitely been a journey getting to that point. So, I would say, if you ever meet somebody that makes you feel like that, then go for it.”

On Being Protective Of His Girlfriend:

Pattinson said that he feels “very protective” of Stewart and that he can see “a lot of [Mirren]’s charm” in her. He continued, “She’s very kind and funny. In some ways, she’s very similar to my mother.” While the actor said that he doesn’t want to “coerce” Stewart into dating him, he also said that he will “never, ever” let someone else hurt her. He said, “You [the public] don’t know where I’m coming from, seeing how long it’s been since I was with my ex-wife. So, I don’t know. I don’t feel like I should have to protect her all the time. [But] if someone hurts her, I will never let them get close to her again.”
