Katy Perry's Prismatic World Tour doesn't kick off again until Sunday. Whatever will we do in the meantime? How about wildly speculating about her romantic life and weighing in with unsolicited advice? Don't mind if we do...

So, since Katy Perry and John Mayer apparently ended their on-again, off-again relationship (again), there are have been a lot of rumors flying around with regard to who the "Roar" singer is dating -- and the candidates are rather diverse.

Allow us to break it down below:

Riff Raff

Pretty soon after John and Katy called it quits, the singer took to social media along with rapper Riff Raff to share snaps from a date they apparently went on. Jody Highroller told TMZ the two went for sushi, bowling and drinks and he'd totally be down to hang again. This G sounds like a Gent.

Diplo

Perry was also apparently linked to DJ/Producer Diplo for a brief spell. Diplo's mom even weighed in on the relationship to Radar Online, saying, "I don’t think it’s a big deal right now. I don’t think they’ll be wedding bells yet. They’re both doing their own things right now and on opposite coasts. He hasn’t discussed it with me, but he did with his dad. He said ‘we’re just hanging out. We’re just friends right now.’ He doesn’t seem to be making a big deal about it. I wondered if it was a publicity stunt. It did occur to me. They both do like the cameras."

Sources have reported that the two have split. Was it something Mom said?

Robert Pattinson

The most recent dude to get the tongues wagging? That would be Mr. Sparkle Vampire himself, Robert Pattinson. Perry and Patterson were seen talking at the premiere of the actor's new movie, which means that they are in love and will soon have babies and grow old together on the front porch of a country cottage in rocking chairs.

You?

Perry maybe-joked that she's "really deep on Tinder" these days. We're not sure why she would subject herself to that cesspool of junk pics and snaps of dudes reclining on drugged-up tigers when she could find her perfect match via facial recognition or whatever, but we do appreciate the egalitarian spirit.

Which dude do you think Katy should come at like a dark horse?
