Okay, I had to take a quick break from work to get this one up. As I was thinking about who I would pick for today, someone came across my mind who was popular in the 80s and 90s. She has matured since then, but is still doing her thing! If you haven't guessed it yet, it is Madonna! Check out her video, 4 Minutes from the Hard Candy album, with a guest appearance by Justin Timberlake!
