Top 15 Most Beautiful Celebrity Couples

12. Katy Perry & John Mayer

Both of the superstar musicians have had their share of some very public breakups and turbulent high-profile relationship in the past.

Katy was married to English comedian and actor Russell Brand, but the two separated after only 14 months, which put the pop singer “in a dark place” for some time, she admitted.

Meanwhile, John Mayer’s high-profile relationship with Taylor Swift didn’t end well either, as they both wrote songs about their nasty love experience. Taylor’s hit was called “Dear John,” while Dear John never denied his tune called “Paper Doll” is about Swift.

And just when we thought that Katy and John found true love in one another, the two both started cheating on each other. On-again, off-again relationship between these two hotties seems to be never-ending. Katy was just recently been spotted getting cozy with Mumford & Sons’ Winston Marshall after their gig in Berlin.

“She wanted to play John at his own game. Katy’s been in a state of constant jealousy during their on/off relationship, and wanted to give him a taste of his own medicine,” a source told Grazia.

It would appear that Katy’s love life is indeed Hot N Cold.
