The flame is out again for Katy Perry and John Mayer. The couple are splitting up again, however, if you think they're a perfect couple there could be a little ember left that could spark that love flame again, but that's not likely.

The split is being reported by multiple sources including Us Weekly and People magazines. One source tells Us Weekly that Katy is "leaving the window open. They have both been so focused on work."

Both Katy and John are professionals and that professional life has apparently gotten in the way of the couple as both of them are focusing on their musical careers and have spent less time together as of late. This isn't the first time the couple has split up, that happened late last year and then reconciled and seemed to be strong especially with comments John made to the Rolling Stone this past January, saying we are "quite happy". And of course, there was the rumor the couple got engaged too.

For now, it appears as if they're going their separate ways.
