Ryan Gosling just got an Oscar nomination for his role in “Barbie,” but the lead actress herself — Margot Robbie — was left out in the cold … and yes, people are pissed.

The Academy Award nominations were announced Tuesday, and RG was on the list for Best Supporting Actor — alongside Sterling K. Brown, Robert De Niro, Robert Downey Jr. and Mark Ruffalo. The black sheep in this group, you could argue, is Ryan … who played Ken.

It was a goofy and even goofier performance — and yet, Academy members seem to think he acted his ass off and is worthy of recognition … something insiders predicted for months.

Now that it’s happened, a lot of folks are happy for the Ry Guy — but even more are angry on behalf of Margot … who got snubbed this morning, and didn’t receive an acting nomination herself. To be fair, there was a lot more buzz around Ryan … but there’s still outrage today.

The argument here for MR basically amounts to … she freakin’ carried that movie, and she showed some range in the titular role as Barbie, going through a roller coaster of emotions.

Some are chalking it up to good old-fashioned sexism/misogyny … and are crying foul.

While Margot missed out, her costar America Ferrera didn’t — she was nominated for Best Supporting Actress, and ‘Barbie’ itself is up for Best Picture. It’s just Margot who got screwed.

So, here’s the question … do you think she deserved to get an Oscar nod, or not???
