After a couple months of casual dating, pop star Katy Perry and musician John Mayer have reportedly broken up.
Multiple sources confirmed the split to US Weekly magazine, with one saying: "She's really upset about it."
Another insider echoed: "She is making it seem like it wasn't serious with John, but she is hurt."
The budding romance between Perry, 27, and Mayer, 34, was first reported when they made an "affectionate" appearance together at Soho House in West Hollywood in June.
At a Beverly Hills pool party earlier this month, a recently-divorced Perry and the notorious lothario "were all over each other, making out," according to one observer.
A friend said earlier this month that the Teenage Dream singer was ready to get serious with Mayer.
They said: "She doesn't want to get her heart broken again, but she feels a real connection and wants to see where things go."
His exes include Jennifer Love Hewitt, Jessica Simpson and Jennifer Aniston.
Meanwhile, Perry divorced Russell Brand earlier this year, and also briefly dated Florence the Machine rocker Robert Ackroyd.
