(CNN) A group of world leaders including Canadian Prime Minister Justin Trudeau, French President Emmanuel Macron and British Prime Minister Boris Johnson were caught on tape Tuesday night seemingly gossiping and joking about President Donald Trump's, um, talkativeness.

"He takes a ... 40-minute press conference at the top," Trudeau can be heard saying while the other leaders nod. "You just watched his team's jaws drop to the floor."

While it wasn't immediately clear that the group was talking about Trump behind his back, it was very hard to conclude they are talking about anyone else. After all, Trump did spend extended periods of time talking to the media during a series of bilateral meetings Tuesday with Macron and Trudeau. And Trump clearly believes the group was talking about him.

"He's two-faced," Trump said Wednesday morning when asked about the comments Trudeau made apparently about him. Trump then, weirdly, added of Trudeau: "I find him to be a very nice guy."

Trudeau admitted Wednesday that he and the other world leaders were talking about Trump.
