Rihanna and Cara Delevigne
Model and actor Cara Delevigne has always praised Rihanna for how many times she has been there for her as a friend. If Cara needed a shoulder to cry on, Rihanna would be there. If she needed advice on a huge career move, Rihanna would give it to her straight. Cara says that her phone calls with Rihanna usually end with, "[She told me] everything happens for a reason. You are going to call me back in a week or two and say, 'You are right.'"
