Pop star Jessica Simpson was left battered and bruised after roller skating in her latest music video "A Public Affair." Simpson filmed the clip with pals Eva Longoria, Christina Applegate and Christina Milian and admits she may have needed a little more practice.

She explains, "Those roller skates weren't my friends! I have bruises all over, including this one on my thigh. My wheel got caught on the stopper of my other skate, and I totally bit it (fell down). I thought I'd get trampled by the skaters behind me. But I was more worried about my hair extensions coming out or my face being demolished!"
