When you're composing music, epic drops and awesome breaks usually translate to a big sounding track and most likely a hit. It's certainly two very important ingredients in EDM. However, for people who make music it takes on a totally different meaning in their personal life.

Looking festive in an ankle-length red dress, Katy Perry appeared on 'Ellen,' with holiday sweater-wearing BF John Mayer, who admitted to being in end-of-year, cozy mode.

You love who you love, regardless of gender, skin color or religion. That should be the governing principle of life in general -- but it's most certainly the case in the song and video for the John Mayer and Katy Perry duet 'Who You Love.'

Even though Katy Perry's first marriage ended in divorce after only 14 months, the singer's relationship with reformed Lothario John Mayer is going so well (despite that hiccup this past spring), that sources say it's pretty certain that they will get engaged.

Off and on couple John Mayer and Katy Perry are firmly back on -- possibly permanently, if he has anything to say about it, because some sources are saying he's asked her to marry him.

John Mayer loves Katy Perry -- and he also loves her massive new single, 'Roar.' The 'Paradise Valley' crooner couldn't stop bragging about his lady love's new song, as well as his collaboration with her, 'Who You Love.'

Katy Perry admitted to being madly in love with John Mayer in her Vogue cover story earlier this summer, despite being broken up at the time. They were seemingly reunited on Fourth of July and now, they get romantic on the song 'Who You Love,' a slow-burning, 'early '80s-inspired soft rock duet.

John Mayer has really turned his act around, and his latest "awww"-worthy deed might just be his kindest act yet.

What the what? These two lovebirds are moving at lightning speed! Not only have Katy Perry and John Mayer reunited (and it feels so good!), but there are now reports circulating that they are moving in together. *Gasp!*

Now that Katy Perry and John Mayer are back on again, the 'Fireworks' songstress is laying down some ground rules for the 'Paper Doll' singer-songwriter. If he wants to date Perry again, he's got to follow some dang guidelines!

In the battle for Katy Perry's heart, right now there are rumors of a Robert Pattinson romance as well as a John Mayer reunion in the works. But Perry's pals are rooting for only one of those guys. Which one?

Katy Perry makes her debut as a Vogue cover girl in July, playing a high-fashion siren/farmer's daughter (we think). But in the accompanying interview, she talks about the loves of her life: ex-husband Russell Brand and on-and-off boyfriend John Mayer.
