'Westworld' star James Marsden reveals he once stalked Dame Helen Mirren!

The Notebook star James Marsden says he once saw Oscar-winning actress Helen Mirren at the Rome International Airport and instead of introducing himself, he followed her and covertly took her picture.

During an episode of The Ellen Degeneres Show, the 43-year-old actor confessed that he he had a huge crush on Mirren and that he still loves her.

"I just love her, I do. I've had a massive crush on her for years," he said. "I was on a flight with her once to Rome, and when I got off the flight, I followed her... To baggage claim, and in a very creepy voyeuristic way, I took a photo of her while she was walking. I was avoiding seeing her backstage because I didn't want her to know that I was stalking her in the Rome international airport."

DeGeneres later invited Mirren to the stage.
