Actor Robert Pattinson saw the ugly side of his fans in fall 2014 when they started sending racist comments on social media to his girlfriend (and rumored fiancée) FKA Twigs, a British singer whose real name is Tahliah Debrett Barnett. It's been a year since Twigs was first bombarded with hate over their relationship, but the nastiness continues to upset Pattinson.

"I was talking to my dad about this and I bet him that if he looked up Nelson Mandela's funeral on YouTube, the first comment would be a racist one," Pattinson told NME in a new interview. "And it was, with like a million upvotes. What I don't get is why. I think it's because most normal people are not commenters—I've never met anyone who's left a comment on anything. It's just demons who live in basements."

Pattinson added that it can be very hard to read comments, but also very difficult to ignore the temptation to see what people are saying about his life.

"You have this weird thing where you end up trying to fight against this faceless blob, where the more you hate it, the bigger it gets, because it's all in your head," he continued.

The performer says his emotions toward the commenters go from hate to wanting acceptance.

"It's always that person who's needling away at you, who you either want to destroy or convince them to love you," he said.

Last year, Twigs told Dazed magazine that she has faced racist comments all of her life.

"People said horrible things about something I had no control of, which was tough," she said. "I never really saw anything wrong with how I looked, it was more that certain people pointed things out to you about yourself. Either your hair's different, or the color of your skin, or your features. Half of my life I've had people staring at me because they think I'm funny-looking and ugly. The other half of my life I've had people staring at me because they think I'm fascinating."
