The night — erm, technically the day in Australia — began with Cameron sharing a pic of his sister and their mother, Sarie Kessler, on the red carpet with the hashtag #excitementoverload on Instagram Stories. And, what pairs better with excitement than bottles, and we mean bottles, of champagne? Like many watching at home, Robbie and his friends definitely did not hold back while drinking bubbly.
When he wasn't busy refilling his glass or screaming (literally) for Allison Janney, Robbie grew pensive to ponder important things, like how the hell Jane Fonda could possibly be 80 years old. And, like many who are deep in the heart of a champagne-fueled discussion, Robbie couldn't help but mention the Illuminati. We've all been there, boo.
The prospect of Fonda teamed up with Jay-Z and Beyoncé in a secret Hollywood-run society didn't distract Robbie from absolutely roasting his sis when she lost the award for Best Actress to Frances McDormand (Three Billboards Outside Ebbing, Missouri), though.
"And a message for Margot. Not good enough are ya?" he wrote, including the hashtag #imstillmumsfavouriteiguess.
Don't worry, the burn was all in good fun. Shortly after, Robbie shared footage of himself emotional with the captions, "Just kidding. I'm literally crying right here."
Oh, sibling rivalry. You keep us young.
For some, this may be your first introduction to Robbie. Yes, you've missed out on a lot of humor and some adorable photos, but fear not! We have a feeling we'll be seeing a lot more of him in the coming years. So far, he's starred in shorts People You May Know and Gifted, and with the power of his comedic chops and charming smile combined, big things in Hollywood could be on his horizon. Who knows, maybe one day Margot will get the chance to put him on blast during an awards show.
