She was recently pictured getting cosy with a hunky Spanish singer during her seemingly never-ending Italian getway.

And it seems the fun never ends in the life of a pop singer as Katy Perry continued to revel in her holiday by enjoying a dip in the azure waters of the Amalfi coast on Friday.

The Bon Appétit hitmaker proved she wasn’t afraid to get stuck in as she put on a scuba diving mask before perusing the Tyrrhenian Sea with her girlfriends.

Opting to flaunt her ample assets during her sun-soaked beach day, Katy, 32, squeezed her sizable bust into a slinky bikini, which was adorned with a vibrant zig-zag motif.

The two-piece’s scanty top boasted a particularly gaping cut between the bust, allowing the beauty to put her generous cleavage on full display.

The design appeared a little too skimpy during some moments, as the star was regularly seen adjusting the number while chatting to friends.

Showcasing her natural beauty, Katy chose to soak up the rays make-up free and left her short, blonde locks free from styling tools.

She donned a navy embellished straw hat to protect her porcelain skin from the punishing rays.

It’s hardly surprising the star – who is scarcely pictured without a glamorous hair and make-up look – chose to keep her style so natural, given that she frequently hopped in and out of the water on the stone-coated beach.

In fact, Katy appeared fixated on the sea as she slipped into its shallower waters and looked in awe at some of its marine life as she looked through a pair of goggles.

After cooling off, Katy retreated to a shady corner of the pebbled beach, where she sat on her phone before turning the pages of Nigel Warburton’s A Little History of Philosophy.

Seemingly having worked up an appetite from all that fresh sea air, the beauty – who recently unveiled a food-centric video for her latest track – tucked into a chicken drumstick and some salad.

Fit for a singing superstar, there was a lavish buffet served up on the beach with the star’s friends seen helping themselves to the barbecue.

She later gave a glimpse of her pert derriere and ample bosom as she bent over to rummage in a cream and brown beach bag.

But in true superstar style, it wasn’t long before the singing sensation headed back to her lavish yacht.

The luxury vessel appeared to possess all of the requirements needed for a fun day at sea, as countless inflatables were seen onboard.

The daredevil star  was seen taking a leap from the deck into the crystalline waters below.

She scrunched her pretty features up as she hilariously prepared for the cold shock of hitting the water.

Katy flashed her taut midriff and peachy posterior as she flew into the air.

Inspired by her show of bravery, her friends were quick to follow her as they took a leap and joined her in the water.

Katy could be seen braving the water as she did her best to keep her platinum crop above the waterline and splashed about.

As she clambered out of the chilly waters, Katy put on a bootylicious display as she flaunted her peachy posterior and flawless legs

She was seen chatting with a few bikini-clad friends as she enjoyed her time onboard.

Enjoying her trip to Europe, the star was toting some binoculars as she enjoyed the luxury on the yacht by sitting back on some cushions

At one point she looked as if she was recreating the famous scene from Titanic as she put on a stunning display at the bow of the boat, looking out onto the idyllic scene.

The Rise songstress later put on a jaw-dropping display as she prowled around the deck of the luxury yacht, revealing her sunkissed lithe limbs and toned midriff.

Her platinum locks quickly dried off in the sun and looked casually chic in a tousled crop.

She showcased her peachy derriere as she turned around to towel herself off.
