Katy and John Split

Oh no! Katy Perry and John Mayer have gone to splitsville!

It wasn't that long ago that John had purchased a really pretty ring for Katy. Now, the couple is no longer together.

Both camps are saying that unfortunately the couple could not make things work while they were both so busy with work. A friend of Katy said that she will always leave the window open for John and that it's, "not over until it's over".

Katy and John restarted their romance last summer after Katy's divorce became final.

Who knows, they may try again for a 3rd time at some point.
