Lance Bass and Joey Fatone from 'N Sync were aboard the Dirty Pop at Sea Cruise and to kill some time they did karaoke.

Most would think they would sing an 'N Sync song or maybe even a Justin Timberlake song to show some love to their band mate, but no.

They chose to sing their arch nemesis' song! "I Want It That Way" by Backstreet Boys.

This was obviously all in good fun and everyone seemed to have a good laugh.

Joey does throw in a cliche joke about the Backstreet Boys that everyone heard when this song was at the height of its popularity, and he even says a profane word at the very end. *gasp*

However, Joey was just in Nick's (from BSB) movie on Syfy and I've seen pictures of all the guys getting along now, so I know its all in good fun.
