The 'Ocean's 8' actress confessed in December that she found it "really hard" to work on the 1994 disaster movie because she fancied the 54-year-old Hollywood star, and now he has admitted that he felt the same way.

During his appearance on 'The Ellen DeGeneres Show', a clip was shown from the film, and afterwards host Ellen asked: "Did you know that she had a crush on you?"

To which he replied: "She obviously didn't know I had a crush on her either."

Asked why they never dated, the 'John Wick: Chapter 3 - Parabellum' star replied: "We were working!"

The pair went on to star in 2006's 'The Lake House', and Keanu gushed: "It was nice to go to work. She's a wonderful person."

Ellen told Keanu that the 'Bird Box' star - who has been dating photographer Bryan Randall since 2015 - is taken now so he has missed his chance.

The comedienne quipped: "I believe she's in a relationship now, the window closed."

Sandra had recalled how she couldn't keep her eyes off the "handsome" and "sweet" actor - who played the lead role of Los Angeles police officer Jack - and struggled to be "serious" during filming the intense flick.

She admitted: "I think about how sweet Keanu Reeves was and how handsome.

"It was really hard for me to be serious [during the filming of 'Speed']. He would look at me and I'd [giggle]."

When Ellen quizzed the 54-year-old actress on whether or not she got to date Keanu, she replied: "Never. I guess there was something about me that he didn't like."
