Singer Katy Perry has reportedly split from guitarist John Mayer just after two months of dating.
Perry, 27, and Mayer, 34, went public about their romance when they made an "affectionate" appearance together at Soho House in West Hollywood in June.
However, all's not well between the two and they have decided to call it quit, reports contactmusic.com. "She's really upset about it," said a source.
Another source said: "She is making it seem like it wasn't serious with John, but she is hurt."
Perry divorced comedian Russell Brand this year, and briefly dated rocker Robert Ackroyd in spring. Mayer's exes include Jennifer Love Hewitt, Jessica Simpson and Jennifer Aniston.
