Have to say, we were more surprised at them setting a June wedding date,  this news that they've since split is far less shocking. Sorry, but this is John Mayer we're talking about.

According to E! Online, the couple broke up a few days ago, and it was Perry who decided on the split - which makes a refreshing change.

The article states: "No other details about what prompted the "Dark Horse" singer's decision were forthcoming, but Mayer was noticeably absent from Perry's side on her recent trip to London and Milan (which went super well). She returned home to Los Angeles on Friday... The duo have been the center of engagement rumors for quite some time now, with the most recent round of are-they-or-aren't-they being sparked by the huge diamond ring Perry was wearing at the Elle Style Awards last week in London. "

See? Nothing good comes from a public collaboration.

For the record, this is - by our calculations - the fourth time the pair have split up.
