Are Katy Perry and Robert Pattinson just friends? Well, a recently leaked video has a totally different story to tell. The video shows Katy Perry sitting on Robert Pattinson's lap while the two sing to the tunes of Karaoke at the Dimples in Burbank, California.

Though the video is from a few years back, it definitely fuels the rumour that Robert Pattinson was dating Katy Perry at one point in time. In the video the two are singing "I'll Make Love to You" and according to People.com the video is hilarious. Reportedly, the two were in the karaoke club celebrating a mutual friend's birthday. Perry gets cozy with Pattinson after she declares, "My chair is too high to make love."

This video if from 2008, the time when Pattinson was not a known actor and neither was he dating Kristen Stewart. Also Katy Perry was single that time. We can just imagine how it would have turned out if Pattinson would not have gone for Stewart and had dated Katy Perry?

They sure would have made a hot couple. However, that is not the case. Robert Pattinson has had a messy public break-up with his long time girlfriend Kristen Stewart and is reportedly dating Sean Penn's daughter Dylan Penn.

Meanwhile Katy Perry is dating John Mayer. The "Roar" singer recently confessed that Mayer was her crush for a long time and she is lucky to date him. Perry told the W magazine "I actually am dating my crush. I had a crush on him for a long time and it so happens we fit together great."

She even told the magazine that she cries on planes. "I always cry on planes. My boyfriend [Mayer] and I call them 'deprivation tubes.' You have a glass of wine, and you're watching a movie, and then, wahhhh" Perry further told the magazine.
