*NSYNC's Joey Fatone Just Trolled the Backstreet Boys in a Boy Band Tip-Off! [PHOTO]

Remember in the late '90s and early 2000's when the ENTIRE world was divided into two groups: those who loved *NSYNC and those who loved the Backstreet Boys? Well even though *NSYNC has broken up and the Backstreet Boys are in Vegas, the rivalry is still strong!

*NSYNC's Joey Fatone happened to be shopping at a local grocery store, when he noticed a different type of tip jar near the check-out aisle:

It's a BOY BAND TIP-OFF Y'ALL! On top of that Fatone called out Backstreet Boys' AJ McLean so this could be the resurgence of an almost twenty year feud! The even better thing is that tons of fans are getting involved and bringing back all the old-school photos the band and their members have ever taken like their "Got Milk?" ads:

AJ from the Backstreet Boys hasn't responded yet, but if the "BOY BAND TIP-OFF" is anything like real life, expect Backstreet Boys to win in the long run!
