Los Angeles, California - Andrew Garfield and Emma Stone were a couple for four years after they met on the set of The Amazing Spider-Man in 2012. Although they remain friends, there are still some things they clearly don't share.

Garfield starred in two previous Spider-Man films, but his showing in the franchise's newest offering, Spider-Man: No Way Home, was kept completely under wraps.

In a new interview on the Happy Sad Confused podcast, the actor detailed how secretive he was about his involvement in the superhero film, and even kept the news from those closest to him.

"Emma kept on texting me. She was like, 'Are you in this new Spider-Man film?'" he said. "And I was like, 'I don't know what you're talking about.'"

Clearly, the exes are still on friendly terms since parting ways in 2015.

"She was like, 'Shut up, just tell me.' ... I kept it going even with her," he laughed. "It was hilarious."

When she finally saw the movie and that her ex was in it, Stone had a salty reply: "You're a jerk."

Garfield said keeping his cameo a secret was both stressful and "weirdly enjoyable."

"There were moments where I was like, 'God, I hate lying.' I don't like to lie and I'm not a good liar, but I kept framing it as a game," he said. "And I kept imagining myself purely as a fan of that character, which is not hard to do."
