Lady Gaga is letting loose!
The 31-year-old singer hasn't been shy on her romantic Costa Rica vacation with boyfriend Christian Carino -- and Friday was no different! Gaga took to Instagram to share a photo of herself by the beach, looking back at the camera with nearly her whole butt on display. The GRAMMY winner accessorized her tiny white embellished two-piece with white sandals and pink sunglasses.
"Vacation Station ☀️," she captioned the booty-baring photo.
Gaga shared a similar pic just hours earlier, showing off her svelte physique in honor of New Year's.
"Happy New Year!🌻," she wrote alongside a shot of herself enjoying Costa Rica.
The pop star wasn't the only star who celebrated the holiday in swimwear. See who else joined the club in the video below.
