Happy Justin Timberlake Day! After months of build-up surrounding his new album, the time has finally arrived. The sexy crooner released The 20/20 Experience on March 19 -- and while it's not an official holiday, it kinda seems like it should be.
So to celebrate JT Day, we're giving you his all-time best dance moves -- from his bleach-blonde 'NSYNC years to his hip-thrusting, crotch-grabbing solo career. Enjoy!
