The Stranger Things actor revealed on the Off Menu podcast on Wednesday that he and his Ghostbusters co-star Mckenna Grace were asked to sing a song for Paul's birthday but he was unsure about the idea. "One of the producers asked me and another person on the cast - McKenna - to sing, like, a song for him. And, like, I just felt like I didn't know if I wanted to do that," he shared. "I don't know if Paul wanted it. He definitely didn't. I think it would've been a really sweet thing on their part.
