Katy Perry - Katy Perry 'Upset' After Being Ditched By John Mayer

One insider close to the California Gurls singer said, "She's really upset about it.She is making it seem like it wasn't serious with John, but she is hurt". Perry, 27, and Mayer, 34, recently made an "affectionate" appearance together at Soho House in West Hollywood on June 19, 2012, effectively confirming their romance. At a Beverly Hills pool party on August 4, 2012, Perry and Mayer "were all over each other, making out", according to one observer. A report earlier this month claimed Perry was ready to get serious with Mayer, with one source revealing "She doesn't want to get her heart broken again, but she feels a real connection and wants to see where things go". Mayer's ex's include Jennifer Love Hewitt, Jessica Simpson and Jennifer Aniston, though Perry was reportedly ready to look past his history with love.

She recently divorced Russell Brand earlier this year, and briefly dated Florence and the Machine guitarist Robert Ackroyd this summer. The pair were spotted getting cosy at the Coachella Music Festival, though it appears the long-distance relationship was too much.
