The 34-year-old "Who Says" singer stepped out in Los Angeles Saturday night at Sky Bar in Los Angeles to celebrate Mindy Kaling's new show, The Mindy Project. While posing for a photo with Kaling, Mayer revealed his short wavy 'do, which he wore spiked up. To enhance the look, the singer wore large beaded necklace with turquoise pendant.

Multiple sources confirmed to Us Weekly earlier in the week that Mayer and Perry, 27, ended their relationship after a couple months of casual dating.

"She's really upset about it," one insider told Us about the "Part of Me" singer. Earlier this year, Perry divorced Russell Brand, and briefly dated Florence + the Machine rocker Robert Ackroyd in the spring.

"She is making it seem like it wasn't serious with John, another insider told Us, "but she is hurt."
