The frontman of N.E.R.D. and super producer Pharrell Williams is really doing big things. The other day, he attened the MET Costume Institute Gala, and partied amongst the biggest stars, including Usher, Diddy, and Oprah Winfrey. Now today, a picture has surfaced of Pharrell with the president of the United States, Barack Obama. Now I know Pharrell’s famous himself, but I would have definitely gotten star struck when I saw Barack.
