I was looking at these pictures of Hilary Duff performing on December 2nd and I noticed that I've seen her shirt before on another celebrity. So after thinking back for a second, I realized that the celebrity who also wore this shirt is Ashanti. She wore it on September 16th to a fashion show. But then after I thought I'd only seen it on Ashanti previously, I found pictures of Keyshia Cole wearing the same shirt while performing at the House Of Blues. That is one popular shirt, it's cute though. I thought I'd share my observation with you all. Enjoy!!!
