Miley Cyrus Calls Out Leo DiCaprio for Bogarting His Vape Pen on ‘Tonight Show’

Miley Cyrus dropped in on “The Tonight Show Starring Jimmy Fallon” Thursday night to weigh in on a variety of topics, including the fact that Leonardo DiCaprio apparently isn’t generous with his smoke products.

Recounting her performance at “Saturday Night Live’s” big 40th anniversary bash earlier this year, “Party in the U.S.A.” singer and outspoken marijuana advocate Cyrus recalled that the “Titanic” star apparently isn’t a believer in the “puff, puff, pass” philosophy.

Estimating that she was separated from DiCaprio by a mere 20 feet or so, Cyrus offered, “He was hitting a vape pen, but it wasn’t him that was making me kind of nervous. I was feeling this emotion, because like there’s an etiquecy [sic] of, like, when we’re there, you need to pass that shit, Leo. And he never did. so that was weird to me.”

“He was bogarting his own vape?” host Fallon marveled, before asking, “Are they all drugs, or are they sometimes just cigarettes?”

“He was looking at me like this [eyes closed to near slits] as I was performing, so he was like, ‘Hey, I really like it.'”

Bad form, Leo, bad form.

During her “Tonight Show” appearance, Cyrus, who took the stage wearing a bizarre, bunny-eared veil of some sort, also did an Emotional Interview segment with Fallon, during which the singer displayed an array of emotions, including super defensive and fake polite.

Cyrus will serve as host on this week’s season premiere of “Saturday Night Live.”

“The Tonight Show With Jimmy Fallon” airs at 11:35 p.m. on NBC.
