Mayer has been sporting a longer, curly hairdo for some time but on Saturday showed off a shorter, wavy cut.

Last week, reports surfaced that he and fellow singer Katy Perry had ended their romantic relationship after only a couple months.

In May, Mayer released his fifth album, Born and Raised, which has spawned two singles: "Shadow Days" and "Queen of California."
