Last night, the boys of *NSYNC reunited for one special occasion… JC Chasez’s big 40th birthday!
Justin Timberlake posted a sweet pic of himself with his former band mates JC, Lance Bass, Joey Fatone, and Chris Kirkpatrick. He captioned it, "JC's 40th... And, if you don't know now you know…”
Lance also added another photo with the birthday boy and wrote, "Happy Birthday #JCChasez !!!! Comment with your bday wishes to JC!!”
It was the first time the guys had reunited since performing together at the 2013 MTV Video Music Awards, where Justin received the Michael Jackson Video Vanguard Award.
*NSYNC was known for their sugary pop hits, including "Tearin’ Up My Heart," "It’s Gonna Be Me,” and “Bye Bye Bye."
