Katy Perry Has Got A Hold On R-Patz's Dimples! Then They Go To A Hotel!

Uh-oh!

Sounds like Katy Perry and Robert Pattinson had quite a night last night…together!

The pair were caught hanging out with friends at Dimples karaoke bar in Burbank. Staffers at the bar said that R-Patz was knocking back quite a few whiskeys while never taking his eyes off of Katy, who belted out a few numbers herself.

Insiders saw the duo “sitting face-to-face, touching foreheads and acting very flirty with each other.” There is even video of Rob and Katy leaving the bar together!

BUT THAT’S NOT ALL!

From Dimples, Rob and Katy then headed to the Renaissance Hotel at Hollywood and Highland! After pulling up around the back and having a smoke with some friends, they then headed upstairs into the hotel…together!

Then, Katy came back downstairs to escort another man that is not her boyfriend up into the hotel! And they were holding hands!

Was there a M├â┬⌐nage ├â┬á ROB going on here?!?!

We know two people who sure as hell won’t be please to hear all this!

While we think Katy could take down KStew with ease, a fight between Russell Brand and Rob may prove to be fruitless. Or fruity, whichever way you look at.

But then again, maybe there is nothing to worry about. Maybe they’re just friends!

Sexy, flirty, drunken hooking up kind of friends!
