This is one of my favorite things to see.  When some of our favorite actors take one of those catchy pop songs and give it a dramatic read, simply awesome.It's always cool to see someone a bit out of their element and knocking it out of the park.  When an actor or actress picks up something by Lady Gaga or Rhianna and gives it their best dramatic take it is something different and awesome.  Here are a couple of them that are pretty new and from a couple people you would never expect.

William Shatner does Rhianna's Umbrella:

James Earl Jones and his take on Justin Bieber's Baby:

Christopher Walken, Lady Gaga's Poker Face:
