President Obama made headlines last week when he spoke out in favor of gay marriage. Now some of music's biggest stars are showing their support for gay rights.

In an interview with CNN on Monday, the Brooklyn born rapper and entrepreneur was asked about Obama's support for gay marriage and shocked many by saying, "I've always thought it as something that was still, um, 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's no different than discriminating against blacks. It's discrimination plain and simple."
