*NSYNC is really turning the nostalgia up a notch this week! After receiving their own star on the Hollywood Walk of Fame [1], the boy band reunited once more during an appearance on The Ellen DeGeneres Show [2] on Tuesday.

Not only did Joey Fatone and Chris Kirkpatrick admit to dating someone that another band member has dated, but Justin Timberlake [5] revealed he once hooked up with a Spice Girl! See what other truths the men revealed in the video above.
