Justin Timberlake: From boy band punchline to American treasure [SLIDESHOW]

Justin Timberlake has gone from boy band punchline as the lead singer of N’Sync, to bestselling solo artist, to actor and back to solo artist again.

JT has been all over the place lately promoting his new album “The 20/20 Experience” — the singer’s first in nine years — with sexy slicked back hair, suits, ties and tuxedos.

Timberlake used to hang out with Lance Bass and Joey Fatone, wear leather vests and emulate Ashton Kutcher’s signature trucker hat accessory (hey, it was the early 2000’s), but now he’s married to a hot actress and rubs elbows with the likes of Jay-Z.

There is no denying the guy has talent, but let’s take a stroll down memory lane to¬†before¬†Timberlake was cool, shall we? (Just wait until you get to the denim-on-denim coordinating outfits he and then-girlfriend Britney Spears wore OUT IN PUBLIC.)
