If you're a Leo (July 23 – August 22), chances are you act like a king or queen — you have an ego, but you know how to use it. House Lannister is a perfect fit for Leos. After all, they emblazon their family sigil, the golden lion, just about everywhere they can. Whether it's swordplay, foreplay, or wordplay, the Lannisters like to show off their skill.
