Emma Watson recently revealed why she has a strict no-selfie policy when meeting fans.

Watson, who stars in the highly anticipated Beauty and the Beast remake, spoke with Vanity Fair recently about grappling with her own stardom and how it caused her to change her perspective on interacting with fans.

"I'd walk down the red carpet and go into the bathroom, I had on so much makeup and these big, fluffy, full-on dresses. I'd put my hands on the sink and look at myself in the mirror and say, 'Who is this?'" she told the publication, discussing the various Harry Potter film premieres. "I didn't connect with the person who was looking back at me, and that was a very unsettling feeling."

Watson changed course after the Harry Potter film series concluded, getting a formal education at Brown University, graduating in 2014 with a bachelor's degree in English literature. She admitted that she wanted to be a normal person again after the whirlwind superstardom of playing Hermione Granger, even though it wasn't a fully successful transition, as she explained in 2011. For example, as Watson recalled, she was in denial about who she was and had become, and in the dating department she ran into trouble because of what she called "the fame wall."

Now, as she's returned to major films again, Watson sticks to her own personal code when interacting with the public, admitting she doesn't love the idea of being tracked.

"For me, it's the difference between being able to have a life and not. If someone takes a photograph of me and posts it, within two seconds they've created a marker of exactly where I am within 10 meters," she explained. "They can see what I'm wearing and who I'm with. I just can't give that tracking data."

But don't be afraid to approach Watson. She will still speak with you about the Harry Potter series and have an in-depth conversation.

"I'll say, 'I will sit here and answer every single 'Harry Potter' fandom question you have, but I just can't do a picture,'" she said. "I have to carefully pick and choose my moment to interact ... When am I a celebrity sighting versus when am I going to make someone's freakin' week? Children I don't say no to, for example."
