Chelsea Clinton talked about starting a family with hubby Marc Mezvinsky Tuesday night. As reported by, the 31-year-old attended a Friendfactor benefit in New York, coming out in support of marriage equality.

"I am proud to be here to support [Friendfactor founder Brian Elliot]," she said. Friendfactor is a new charity group that uses social networks to effect positive changes for gay rights. "I certainly believe that all of my friends, as Marc and I did, should have the right to marry their best friends."

Clinton added: "I certainly believe that those of us who are straight cannot expect our gay friends to do this on their own. And I certainly expect our straight friends to help us achieve that for all New Yorkers, for all Americans, and for all the children that at least Marc and I hope to have someday."
