Out basking her bikini clad body for the second day in a row, Katy Perry took to her hotel rooftop pool in Miami Beach, FL on Friday afternoon (July 27).

Clad in a green and gold bandeau swimsuit, the 27-year-old "Firework" pop star spent most of the day soaking up the sunshine alongside her 91-year-old grandma - though she managed to squeeze in a little bit of flirting with some of the fellas before heading back to her posh suite.

During her Sunshine State getaway, Katy found time to post a message expressing her disdain for the Internet, as she wrote, "Someone please pull the plug on the internet. Does it really better us as humans? #writealetter #whoactuallytalks #thistweetishypocritical"

Perhaps Miss Perry is unhappy over her love life being constantly dissected on the web - as she's most recently been tied to lady-loving lothario John Mayer.

The romance rumors come after Katy and John enjoyed a "lovey-dovey" tryst back on June 19th, of which a source told Us magazine, "They were affectionate, holding hands and cuddling!"
