Aubrey Plaza knows what it's like to have a stalker.
ET's Katie Krause spoke with the 33-year-old actress and her co-star, Elizabeth Olsen, at the Ingrid Goes West press junket held at the Fairmont Miramar Hotel & Bungalows in Santa Monica, California, on Thursday, where they spoke about having online stalkers and filming together.
In Ingrid Goes West, Plaza plays a crazed social media stalker who moves to Los Angeles to befriend her Instagram obsession Taylor Sloane (Olsen).
"I had kind of an online Twitter stalker, kind of, person that was around," Plaza told ET. "This was a couple years ago and then I was shooting a movie in Seattle and we found out that that person had applied to be an extra."
"Did you get a restraining order?" Olsen asked. "I don't remember," Plaza replied.
"But it's fine. I'm fine," the Parks and Recreations alum added. "But yeah, there was something about, there was a lot of, like, weird, creepy messages about cats. I don't know what he was talking about. He really wanted to have dinner with me dressed as a cat or something."
