Fresh off the success of his latest film UnchartedTom Holland stopped by Late Night With Seth Meyers on Monday, where he let slip a secret about one of his Spider-Man: No Way Home co-stars.

While discussing the bond that he shares with his fellow Peter Parkers (previously played by Tobey Maguire and Andrew Garfield), Holland revealed that one of the actors wore butt padding in their suit.

“I’m gonna give you a spoiler and I’m not gonna tell you who [it is], but one of us has a fake ass in their suit. You can figure that out for yourselves,” Holland joked. “I remember being on set and being like, ‘Wow, hang on a minute. That’s not real!’”

All jokes aside, Holland maintained that it was an honor to share the screen with his predecessors. 

“It was the most incredible experience of my career,” he said. “To share the screen with them, you know, playing Spider-Man, while being a wonderful experience, like completely life-changing, it also can be quite alienating.

The 25-year-old actor added, “When you’re 19 and someone gives you the opportunity and your life changes, it’s quite hard to figure out how to navigate. So to almost have two older brothers who had been through it before me, to be able to share that experience with them was amazing.”

While Uncharted topped the box office this weekend with an estimated $44.1 million, No Way Home remained in the top 3 in its 10th weekend, as the blockbuster Sony film pulled in another $9.1 million across four days.

Last week, No Way Home beat out James Cameron’s 2009 blockbuster movie Avatar to become the third biggest domestic release ever.
