Breaking up is hard to do... even the third time around!

Katy Perry and John Mayer have called it quits again after briefly reconciling after the pop star finished her tour earlier this year, Radar reports.

"Katy and John reconnected once she had a break in her Prismatic World Tour. So, for those few months they had a great time, pretending that it would last — and of course it didn’t. The reason they have split in the past is because Katy gets busy. John can’t handle the lack of attention, and she can’t handle the trust issues she has when she’s so far away," the source dished about the couple's issues.

The lovebirds have been on and off since the songstress' marriage to Russell Brand ended in 2012. The pair last parted ways last February, but then were spotted in January of this year spending time together. The "Gravity" crooner even accompanied his lady love to the Super Bowl this year.

If they're really dunzo, we hope those rumors that the brunette beauty has a bun in the oven aren't true!
