We take it back: Katy Perry has more than one deliciously dark secret in her arsenal. She once sang a Boyz II Men duet with international heartthrob Robert Pattinson, as evidenced by a new YouTube video that has mysteriously surfaced today thanks to user “likeafooool.” A Robert Pattinson blog sources the brilliant rendition of “I’ll Make Love to You” to a 2008 birthday party forRaising Hope actress Shannon Woodward at Dimples, a Burbank, California, establishment that credits itself as “the First Karaoke Club in America.” It is not, however, the First Karaoke Club in America where Boyz II Men has been wailed vaguely off-key into a microphone.

Some highlights:

0:00 to 1:30 Perry’s lumberjack hat and the omnipresent disco ball.

0:15 Robert Pattinson halting his American-accented, smooth R&B delivery of “Girl, your wish is my command” to thank a partygoer for bringing him a drink.

0:41 Katy Perry stopping to observe, “This chair is too high to make love.”

__0:59__Perry drinking from Pattinson’s cup while he stumbles through the “Let’s go slow, I have nowhere to go” lyric.

1:07 Perry recoiling in subtle horror as Pattinson wails, “It’s going to be a long night!” like a wounded (but adorable!) animal.

(Seeing Pattinson and Perry’s chemistry in the video below, it now makes more sense why Katy Perry felt the need to let Kristen Stewart know that she was not carousing with her ex-boyfriend following their highly publicized break-up this summer.)
