Sailor Brinkley Cook & Alexa Ray Joel?

This week we're talking about Alexa Ray Joel (the daughter of Christie Brinkley and Billy Joel), Sailor Brinkley Cook (the daughter of Christy Brinkley and Peter Cook), and why it's probably hard being the daughter of someone who can literally walk on water. PLUS: Splits we're sad about, splits we're not sad about, and our probably-untrue theory about why Joanna Krupa Instagrammed a photograph of herself in the bathtub. (SPOILER: It involves Brandi Glanville.)
