Say hello to the arm candy know as Penny Lancaster. If you’ve never heard of Penny, don’t be alarmed. She is actually the 38 year old wife of singer Rod Stewart—who just so happens to be 64. So yeah, I think the term “arm candy” pretty much sums it up, especially since she is a former model. But I will give Penny Lancaster this, she’s got a better body than many 28 18 year olds. So props to Rod and to Penny for that Jessica Alba like pose!
