Katy Perry and John Mayer reportedly split-again-after engagement rumors swirl.
According to E Online, a source close to the couple reported that Perry initiated the break-up within the last few days.
The pair, who have had their fair share of ups and downs since they started dating in the summer of 2012, seemed to have been pretty solid lately. After getting back together in March of last year after a brief split, the two collaborated on the song "Who You Love", off of Mayer's most recent album, as well as made several appearances together, including talk shows and award shows.
Last week, Perry wore a huge diamond ring, which ignited engagement rumors between the couple, who have not been seen together since Valentine's Day.
According to New York Daily News, the split comes as a result of the stress that comes with Perry's upcoming world tour.
Perry has made several appearances in London, Milan, as well as Los Angeles without the company of Mayer.
