Beyoncé and Jay Z
Jay Z voiced his support for same-sex marriage at a Budweiser music festival press conference: "I have always thought of it as something that is still holding the country back. What people do in their own homes is their business, and you can choose to love whoever you love. That's their business. It is no different than discriminating against blacks. It's discrimination, plain and simple."
Beyoncé, on the other hand, kept it short and sweet on her Instagram: "If you like it you should be able to put a ring on it #WeWillUnite4MarriageEquality".
