John Mayer once referred to his ex Taylor Swift writing about their relationship and their split in a song as “cheap songwriting” but we’re going to call his method of dumping Katy Perry (after a very short and public romance) a cheap move.

Mayer reportedly broke up with the ‘Wide Awake’ singer via email.

Hey, at least it wasn’t a text, right? Still, a guy has to have no cajones to break up with a girl that way.

Mayer, who has dated a string of Hollywood beauties, ranging from Jennifer Aniston to Jessica Simpson, was apparently not impressed by Perry’s wild lifestyle and thus ended their fling. A source said he grew “tired of Perry’s hard partying and decided to pull the plug,” according to Us Weekly (quotes courtesy of Hollywood Life.)

The singer/songwriter/guitarist, who spoke about his splits with Aniston and Simpson in the media, was apparently so sick of the partying that he didn’t want to do the deed in person. He dumped her over email and the source continued, “She was furious and really hurt. She was into him, but he wasn’t feeling it.”

So. Not. Cool.

Mayer and Perry were seen at Hollywood hotspots and canoodling in a pool. They dated about a month, right after her divorce from Russell Brand was finalized, but it didn’t last. It seems like it was just a quick summer fling, even though we thought they were destined to be together when it was revealed that they had a date the night before she met (and fell in love with) Brand.

Onward and upward, Katy!

PopCrushers, what do you guys think of John Mayer’s method of ending his relationship with Perry? Remember, neither ever confirmed the relationship, but still. Dumping-by-email sucks!
