Why Did Carrie Underwood Paint Her Nail Purple? [PHOTO]

Did you notice this on Carrie Underwood's Instagram?

It's no secret that Carrie and Jana Kramer are friends, and Jana is amazing advocate for victims of domestic violence. So, naturally, during National Domestic Violence Awareness Month Carrie decided to join Jana and show her support and bring awareness to the cause herself.

I like the new look! I like the cause/reason for it even better!

Have you done anything for National Domestic Violence Awareness Month?
