Justin Bieber’s definitely all grown up and sounding more like Clint Eastwood than a young pop star when some teens in Bev Hills ticked him off in a fancy hotel.
The new clip circulating on social media shows the singer-songwriter Thursday in the lobby of the Waldorf Astoria, a popular celeb hot spot, where he confronted the pack of teenagers.
In the vid, he’s angrily asking the teens what they find so funny — very Joe Pesci from “Goodfellas,” we gotta say — waving them away from him while hotel staff appears to be shooing them out the door.
Witnesses tell TMZ he had good reason to be upset … he was meeting his pregnant wife Hailey Bieber for lunch at the hotel when 8 teens — who were at the hotel for a bar mitzvah — started following him around and yelling at him.
