Justin Timberlake
We don't really need to tell you what JT has been up to since his NSYNC days, because he has been absolutely killing it. His debut album, Justified, released at #2 on the Billboard 200 charts. After his FutureSex/LoveSound album, Timberlake took a music hiatus to focus on acting, taking on roles in Alpha Dog, The Social Network, Friends with Benefits, and more. We really could go on and on about Timberlake, but you get the gist.
