Here we go again. Revolving relationships always seem to happen in Hollywood (right, Jelena?) but this one making us scream out “WTF?!”

Katy Perry and John Mayer have reportedly rekindled their relationship, after splitting a couple months ago. According to sources, the couple are “back on” and just enjoying their “casual” relationship. We’ll let Chelsea Briggs take it over and explain our confusion in this week’s WTF Wednesday!

So, when did Katy and John decide it was such a wonderful idea to get back together? Apparently the two were sighted at Katy’s Memorial Day party last week. “They are just hanging out,” a source told E! Online. “They are not putting a label on it.”

And it seems as though Katy and John have been spending more time together than we thought. In fact, the two have been having sleepovers here and there, though they haven’t been spotted together since last March.

Katy, listen girlfriend, are you sure this is a good idea? You know that saying “There are plenty of other fish in the sea?” Yeah, that’s true and totally applies to this situation. John doesn’t have the best reputation in Hollywood (he likes to give all the dirty details of his past relationships) and Katy, you could do so much better.

What do you think about these two getting back together?
