Old pals Katy Perry and Robert Pattinson were hanging out at a party when the duo decided to take the mic at the karaoke station and tackle an old Boyz II Men song.
You can tell Katy is purposely trying to disguise her amazing voice, which she actually pulls off pretty well. As for Robert, well, it's a good thing he's such a great actor!
The performance actually happened in 2008, although the video is only now beginning the journey of becoming a viral sensation.
Hey, better late than never, we say...although Katy and Rob might disagree!
