Monday night on Dancing With The Stars, it was "Boy Band and Girl Group" night, where each contestant did a dance to a song by a boy band and a second dance to a song by a girl group... so it was only fitting to have a member of a boy band sitting on the judge's panel.
Enter Joey Fatone, NSYNC member and Dancing With the Stars contestant in 2007 and again in 2012.
As part of the opening number, Joey joined in on the dancing fun as NSYNC's "Tearin' Up My Heart" played... annnnd as Joey did a split jump, his pants did a split of their own! Later in the show, host Tom Bergeron called Joey out and encouraged fans who were recording the show to go back and watch. And there it is in all it's glory, 2:28 into this video...
"Tearin' Up My Heart???" More like "Tearin' Up My Pants!!!"
