Whether they're consoling you over a bottle of Merlot or awkwardly confronting you about finding your BDSM contract, every rom-com needs its sassy girl friend. Fortunately The River's Eloise Mumford has joined the 50 Shades of Grey cast to sass it up as Kate Kavanagh, Anastasia Steele's roomie and bestie. Apparently Kate doesn't like Christian Grey one bit! Finding that contract lying around probably didn't help. Keep those things in a locked drawer, people.
