Katy Perry and John Mayer Split

Are Katy Perry and John Mayer over already?
The “Roar” singer allegedly broke up with her musician beau at some point within the last few days, according to E! Online.
The couple’s split comes on the heels of engagement rumors.
Perry added fuel to that speculation in recent weeks by repeatedly flashing a diamond ring on her all-important finger.
Mayer and Perry have broken up numerous times since stepping out publicly in 2012, most recently around this time last year.
Maybe it was that Miley Cyrus kiss that was the last straw?
