Los Angeles, Jan 21 (IANS): Actress Kristen Stewart says US President Donald Trump was earlier "obsessed" with her.

Trump had in 2012 commented on Stewart's personal life.

"He was mad at me a couple years ago, really obsessed with me a couple years ago, which is f*****g crazy," Stewart told variety.com.

"I can't even understand it. I literally cannot even understand it. It's such far-out concept that I don't want to believe that actually is happening. It's insane," she added in reference to Trump's swearing-in as the US President.

Trump's presidential inauguration took place on Friday.

He had tweeted in 2012: "Robert Pattinson should not take back Kristen Stewart. She cheated on him like a dog & will do it again -- just watch. He can do much better!"

When asked how Trump's tweets made her feel at that time, Stewart replied: "At that point, he was just, like, a reality star. I had no reference. It wasn't like really a thing. But in retrospect, somebody reminded me of that and I was like, ‘Oh my gosh, you're right!'"

Stewart, who's not on Twitter, quipped: "He's probably, like, going to tweet about this."
