After NSYNC — one of the best-selling boy band in history— broke up in 2002, Timberlake embarked on a solo music career. He has since released five studio albums.

Timberlake began acting in the mid 2000s, playing his first major role in the 2006 film "Alpha Dog." He has since starred in a range of movies, from "Friends with Benefits" to "In Time," and played roles in critically acclaimed films like "The Social Network" and "Inside Llewyn Davis."

Timberlake is now married to actress Jessica Biel, and the couple has a son together.

NSYNC formed in 1995, and originally consisted of members Justin Timberlake, Chris Kirkpatrick, Joey Fatone, Jason Galasso and JC Chasez. The band name is a play on the last letter of each original member's first names.

The group released three studio albums, coming out with classic pop songs such as "Pop" and "Bye Bye Bye." Their second CD sold 2.4 million copies in its first week, a record that, as of 2015 had not been broken.

Though the band broke up in 2002, they had a reunion in 2016 to celebrate JC Chasez's 40th birthday. Fans have been hoping for a reunion tour since.
