The "Come & Get It" singer stole the spotlight in two stunning ensembles at Leonardo Dicaprio's Foundation Gala in Saint-Tropez, France on Wednesday.
The 22-year-old hopped off a boat wearing a brown full-length gown that came fully equipped with a thigh-high slit and beautiful draping. She paired the dress with bronze pumps and slicked-back hair for the black tie affair.
The brunette beauty later changed into a black, cleavage-baring frock that she paired with a sexy fishnet veil.
The evening raised over $25 million for The Leonardo DiCaprio Foundation, which is dedicated to protecting wildlife around the globe.
Selena is having quite the vacation across the pond!

Sounds like she's having a birthday week she won't soon forget!
