Couple Katy Perry and John Mayer Split

Singer Katy Perry and her new beau, John Mayer, have reportedly split. 

After a couple months of casual dating, the guitar-playing musician and the pop star have broken up.

Multiple sources have confirmed to US Weekly magazine, with one saying; “She's really upset about it.”

Another insider said; “She is making it seem like it wasn't serious with John, but she is hurt.”

The budding romance, with 27-year-old singer and 34-year-old John was first reported when they made an "affectionate" appearance together at Soho House in West Hollywood in June.

The media began to keep tabs on the new couple, interested to see if it would last as Mayer is known for his charm with the ladies. He has previously dated celebrities Taylor Swift, Kim Kardashian, Jennifer Aniston, Cameron Diaz, Jessica Simpson, Jennifer Love-Hewitt, eh-hem, the list goes on…

At a Beverly Hills pool party earlier this month, a recently-divorced Katy and the serial woman-dater “were all over each other, making out,” according to one witness.

A friend also said earlier this month that the 'Teenage Dream' singer was ready to get serious with John.

She said: “She doesn't want to get her heart broken again, but she feels a real connection and wants to see where things go.”

Meanwhile, Katy divorced Russell Brand earlier this year, and briefly dated Florence + the Machine rocker Robert Ackroyd in the spring.  

Looks like her wish has yet to come true...
