Kristen Stewart addressed the "crazy" time she was shamed by Donald Trump on Twitter.

While participating in an interview during the Sundance Film Festival in Park City, Utah on Friday (January 20), she was asked about a tweet Trump posted in 2012.

"Robert Pattinson should not take back Kristen Stewart," the now-president tweeted. "She cheated on him like a dog and will do it again—just watch. He can do much better!"

"He was mad at me a couple years ago, really obsessed with me... which is f---ing crazy," Stewart said. "I can't even understand it!"

The actress added that "at that point, he was just a reality star. I had no reference, it wasn't really a thing," before quipping, "He's probably gonna tweet about this!"

When she was asked about women being concerned about Trump's presidential agenda, she told Variety, "They should be! I've never been the most politically charged person, but at this point, it's not political—it's f---ing so humanitarian."
