Joan Collins is one hot momma.
Even though she's 78-years-old, she seems to defy age. The actress/author wore a thigh-skimming silk dress, and showed off her amazing legs, while promoting her book The World According to Joan at Selfridges in London.
Joan once said that sex was better than Botox, and honey, we believe you! You look incredible!
