All five members of 'N Sync, including Justin Timberlake, reunited for the former pop band member JC Chasez's 40th birthday here.
The former boy band celebrated the milestone at a small private party here on Monday, said a source, reports usmagazine.com.
Around 50 people, including Timberlake's wife Jessica Biel, were in attendance.
The "Can't stop the feeling" singer, 35, took a snapshot with Chasez, Lance Bass, Joey Fatone and Chris Kirkpatrick to mark the occasion.
"JC's 40th... And, if you don't know now you know," he captioned the image.
Kirkpatrick, 44, shared the photograph via Twitter. "Happy 40 son," he wrote.
The longtime friends previously reunited during the 2013 MTV Video Music Awards.
