The supermodel sisters were spotted jet skiing on the open waters of the Mediterranean sea on Tuesday, hours after Gigi hosed herself off in the shower.
Gigi was photographed straddling the Yamaha while away in Mykonos and showcasing the goods she was blessed with.
Wearing a teeny, tiny black two-piece, Gigi's sun kissed cakes were out in full force and got plenty of vitamin D during their water excursions.
After Bella hid the water, the newly blonde bombshell decided to cool off with a frozen drink beachside with her girlfriend.
Sporting the smallest string leopard print bikini, Bella, 22, seemed ready to party and didn't play when it came to day drinking.
Showing off her striking body, the runway queen sported a gold waist chain to draw focus to her curves.
Bella stayed fresh in the sunshine while riding her jet ski.
Taking the reigns with her friend straddling behind her, the duo wore life vests while Bella navigated the monster water vehicle.
While the younger Hadid's motor skills were impressive, nothing beats Gigi on her jet ski.
The model, who's 24 years old, even stood up to slice through the waves.
Their jet ski adventure comes just hours after Gigi hosed herself off in the outdoor, stoned shower.
Sporting that small bikini, she posed dripping wet while water flowed down her half-naked body.
"GÃkonos," she captioned the shot, changing the name of their Mykonos vacation.
That wasn't the only time Gigi get wet in the day.
She also took a dip in the sea to cool off after their intense day out on the jet skis.
Bella followed her sister's lead, threshing through the sea in her leopard print bikini.
Gigi and Bella Hadid have been gracing us in their bikinis while in Greece for several days, showing off their best assets while sporting all kinds of tiny little two-pieces.
Summer's never been better!
