lance bass aj mclean kathy bravo Lance Bass and Kathy Griffin sing with AJ McLean on 'I Want It That Way'It was a boy band showdown on Thursday’s (June 15) episode of Kathy Griffin’s Bravo talk show, “Kathy.” Lance Bass from ‘N Sync and AJ McLean from Backstreet Boys stopped by to show they’ve still got their singing and dancing skills.

Kathy and Lance sang backup for AJ on an a cappella rendition of Backstreet’s 1999 hit “I Want It That Way,” while Lance taught his fellow former boy bander how to do ‘N Sync’s famous “Bye Bye Bye” dance from their 2000 song.

Check out the videos of the walk down musical memory lane.

Which band would rather see in concert now: ‘N Sync or Backstreet Boys?
