The Chained To The Rhythm star left very little to the imagination as she poured her curves into the pastel two-piece as she took some time out from her busy schedule.
Her ample ᴀssets took centre-stage in the racy halter-neck number, which looked as though it could barely hold everything in place.
Katy’s ʙosoм risked spilling out of the dangerously low-cut style as she stretched out on the sand and frolicked around in the sea.
The 32-year-old’s toned stomach was also impossible to miss as opted for a pair of tiny patterned briefs with tie detailing at the hips.
As the waves rolled over her curvaceous figure she could be seen shrieking in shock along with her four companions.
It seems the singer is making the most of her time in Mexico and was only too happy to share snapsH๏τs of her break with her 64.3 million followers.
Katy captioned the idyllic snaps on her Instagram page: “Goofy goddesses.”
They came after she shared a hilarious clip of herself flaunting her enviable figure in a barely-there ʙικιɴι as she paraded around the beach with a coconut on her head.
She could be seen flashing the peace sign as she strolled across the sand in the revealing two-piece.
Across the video, Katy wrote: “When life’s a bisch, go to the beach (sic).”
