In one set of photos, the look-alike girls can be seen wearing matching rainbow-colored mermaid tails and big smiles as they stretch out on the lawn, dip their fins in the pool and enjoy their special occasion and their equally special aquatic transformations.

Madonna captioned the shots, "The After Party," which means those adorable pics were from the celebration after the celebration.

As for the main event, the costumes for that were just as cute.

Stella and Estere dressed up as the crime-fighting Parisian teens from the animated series "Miraculous: Tales of Ladybug and Cat Noir" — and that part of the celebration spilled over into the pool, too.

The photos revealed a fleet of inflatable ladybug floaties and even offered a glimpse of the girls' cake — an Eiffel Tower topped creation that matched their superhero costumes.
