Cape Town – Justin Timberlake and Jimmy Fallon have been BFF’s for a very long time.
The pair known for their awesome music collaborations took us way back to summer camp in 1997 on The Tonight Show.
Jimmy still had braces and Justin just grew facial hair and hair in some other places too.
In true summer camp style the two could not help themselves from singing out loud after lights out even though they knew they would be punished.
