It's boy band mania today -- with two guys from the biggest boy bands of the '90s celebrating their birthdays!
*NSYNC's Joey Fatone, who was 18 when the band formed back in 1995, turns 35-years-old today. At 35, Fatone is the 3rd oldest in the former group -- behind 40-year-old Chris Kirkpatrick and 35-year-old JC Chasez.
The other former teen star celebrating today is Nick Carter, of the other big boy band, Backstreet Boys. He turns 32!
Now back in the day, you were either a bigger *NSYNC or BSB fan -- we want to know which team you were on!
