The Gravity star looked trim and fit in a tiered burgundy strapless Lanvin dress enhanced with a bedazzled belt around her waist.
It's a shame she didn't wear this sophisticated but seksi outfit at the Golden Globes on Sunday, but at least we get to appreciate it now!
On top of that, Sandra's straight locks and flawless skin made her look easily ten years younger than she is.
We think she's gained back her mojo, and we hope she kills it at the Oscars in March!
