Whoa!  What a story to wake up to!  Katy Perry and John Mayer are OVER!  Supposedly she broke it off with him! 


E! News exclusively reported the news early this morning from a reliable source.


John was noticeably absent from her recent trip to London, which had people talking, but we didn't think it was a breakup!  Especially since they have the song together! 


Maybe she wanted to get engaged and he said, no way. Oh love.
