Stop it Katy. You're making a mistake. You've done this before and it didn't work. Stop.

Katy Perry and John Mayer are pretty much confirmed as being back together after she Instagrammed this photo of the two yesterday, with the caption 'Whose broad stripes and bright stars?!'. The answer is TRAGEDY'S Katy. That's who they are.

The two were spotted mashing faces at a bar in New York recently after they split last March. According to Life & Style, 'She said it will only work if he follows some of her rules,' one of which is 'Getting rid of his old girlfriends’ numbers and no more texting them' according to a blabber.

Katy. We wish you luck. You'll need it.
