Sandler also refuted reports that the purpose of the dinner was for Bieber to get advice on breaking into the movie industry.
"I don't know who said that, but that's some weird story that they made up," he clarified. "That's not it at all. We just hung out. We just wanted to go to dinner, me and David Spade and Dustin [Hoffman], and Dustin said no, so it was just me and David."
Hoffman later hilariously told ET he actually didn't know who Bieber was.
"Who is he?" Hoffman replied when asked what his favorite Bieber song was.
"It doesn't matter, you'd like him," Sandler quipped.
