Now that Justin Timberlake has cut back on his Tom Ford suits, can he stop wearing that damn hat as well? It never leaves his head these days. Perhaps he's trying to grow out his relaxer or just didn't have the time to go in for his mizani keratin treatments. That could only be a good thing right? Curly hair is your calling JT, don't fiiiiight it. Anyway, check out his entire 100-minute set at this weekend's 'Rock in Rio' music festival. He brought his '20/20 Experience' to the bill performing new cuts off the project and older songs from previous. He also covered INXS’ 'Need You Tonight' and spat some bars over Jay Z and Kanye West’s 'Ni**as in Paris'. If you enjoyed his set, his '20/20 Experience' world tour kicks off on October 31st in Montreal. And the second half of his album 'The 20/20 Experience' drops in stores on September 30th. Get into the action below!
