The Social Network debuts today, and one of the reasons I've been particularly curious to see it for myself is Justin Timberlake's performance. The guy has been trying the acting thing for a while, yet I can't help but long for the days of JT, the singer. So for my latest Hot Buzz Time Machine, I bring you the video to "Cry Me a River." Remember the ruckus it caused way back when (thanks to a very impressive Britney Spears doppelganger)? It's hard to believe this was nearly eight years ago — it was my jam! Just watch.
