Katy Perry and John Mayer's on-again/off-again relationship is, once again, off.
The music superstars have split after a second stint of dating - this time around, they lasted for seven months.
Katy, 28, and John, 35, previously dated during summer of 2012, before splitting (for the first time) in August 2012.
The news of the breakup comes just a few weeks after the often-outspoken John opened up to "CBS Sunday Morning" about his relationship with the "Firework" pop star.
"For the first time in my life I don't feel like I'm in a celebrity relationship. I really don't," John said in February. "For me it feels like something that's very human."
During their second go-around, Katy and John made no attempts to hide their love for each other, often spotted out and about together in public and posting photos of themselves in numerous online shots.
The couple was affectionate towards each other during Clive Davis' annual pre-Grammy gala and Katy & John were photographed together attending President Barack Obama's inauguration in Washington, DC.
Katy and John first began dating after her divorce from Russell Brand, which was finalized in February 2012.
