We have always known that Katy Perry can sing but have you seen Robert Pattinson sing?

E! News reported a video where Perry and Pattinson sang a duet of Boyz II Men's "I'll Make Love to you."

The video clip is allegedly filmed at the Burbank, California karaoke club named Dimples a few years ago. At one point in the video, the "Roar" singer is sitting in the lap of the Twilight actor.

John Mayer doesn't need to be jealous as Pattinson and Perry have never been romantic. In fact, Perry said to Elle in August that she's very comfortable with Pattinson that she actually farts in front of him. Perry added: "I never, ever fart in front of a man I am dating."

It seems that Pattinson has another talent up his sleeve as he can certainly hold his own with Perry.

The only bad thing about the video is that it's only a minute-and-a-half long.

Here's to hoping that the public can see another video from these two friends in the future or even to singing live?

The two are busy with their own lives. Perry performed for 2,000 students and staff at the Lakewood High School in Lakewood, Colorado as a part of Good Morning America's "Roar" With Katy Perry Contest.

Meanwhile, Pattinson is selling his L.A. mansion which he once shared with ex-Kristen Stewart.
