The Bon Appétit singer is on a whirlwind tour of Europe, and she’s made sure to flash the flesh every step of the way.

** CELEBS FLASH EVERYTHING IN KNICKERLESS TREND **

After parading her mega cleavage on the beach earlier this week, Katy has stripped off once again in Siesto Fiorentino, Florence.

Letting her sizeable assets take centre stage, the starlet rocked a teeny purple two-piece that clung to her curves.
No doubt causing fellow holidaymakers to take a double look, the 32-year-old embraced the mother of all boob spills in the low-cut design.

The body confident babe also displayed her toned stomach as she enjoyed her day out.

Making sure to protect herself from the sun, the California native wore a straw hat with floral detailing.

She added a touch of glamour to her beach look with statement red lipstick and large hooped earrings.

While the singer is currently promoting her album Witness, she seemed happy to indulge in some down time.

Taking the load off, the peroxide blonde beauty could be seen lying down on a beach towel.

However, Katy was caught in a compromising position when she was snapped with her hand placed in between her open legs as she appeared to scratch an itch.

But she wasn’t lying down for long, as the active starlet made use of her surroundings and went into the water for a solo paddle boarding session.

The Swish Swish singer untied her bikini top as she made an adjustment.

As fans will remember all too well, the songstress engaged in a flesh-flashing paddle boarding moment last summer with then-boyfriend Orlando Bloom.

The Brit actor made headlines worldwide as he dared to go completely starkers, while Katy opted to keep her bikini firmly on.

During a recent appearance on Australia’s radio show Kyle and Jackie O, the musician spoke about the now-infamous moment with her ex.

Revealing the inspiration behind the naked stunt, she explained: “He [Orlando] wanted to show off for the people on the shore. He thought it was funny.”
