Leonardo DiCaprio
became a trending topic during Sunday night’s Golden Globes for one particular moment -- and no, we’re not talking about his win for The Revenant.

The 41-year-old actor made quite a face when Lady Gaga, who was walking toward the stage to accept her award for Best Actress in a Limited Series or TV Movie, touched his back as she walked by.

“I just didn’t know what was passing me -- that’s all!” the Revenant star admitted.

DiCaprio won a Globe himself for his harrowing performance in the gritty film.

“This is a type of film that you won’t see coming out of the Hollywood studio system very often,” he said. “It’s an epic art film and I’m just so happy it got recognized tonight.”

The Revenant
, which co-stars Tom Hardy, took home three awards, including Best Director for Alejandro G. Inarritu and Best Motion Picture, Drama.

“I want to make more movies like this, and I want the studios to take more chances on movies like this,” DiCaprio added.
