It's that post-Oscar glow, baby!
And she's meeting the one and only freaking Rihanna!!
THIS. IS. EPIC.
But Rih, in her incredible ensem, wasn't the only star to share in Lupita's radiance. The actress looked adorably proper in a collared shirt worn with a burgundy coat and crinkled pink skirt from the brand, and she was also joined by Margot Robbie, Elizabeth Olsen, and Bella Heathcote, all of whom proceeded to take selfies with the award-winner.
What a fabby few months it's been for Lupita, and we have a feeling it's only going to get better and better!
Check out more pics of the fun in the gallery (below)!
