Katy Perry is single and ready to mingle -- with Mickey Mouse, Buzz Lightyear, and the rest of the Disney gang.
The "Part of Me" singer, 27, hit Disneyland -- aka the Happiest Place on Earth -- with pals Saturday, just a few days after news broke that she and John Mayer had gone their separate ways.
On Saturday evening, Perry strolled around the Anaheim, Calif. park with a group; she and a girlfriend took a spin on the Buzz Lightyear ride and rocked Mickey Mouse ears inside a restaurant.
Last week, multiple sources confirmed to Us Weekly that the pop singer and Mayer, 34, had split after a fun several weeks.
"She's really upset about it," one insider told Us.
Echoed another source, "She is making it seem like it wasn't serious with John, but she is hurt."
