Busy Philipps is the latest celebrity to join the Human Rights Campaign's (HRC) Americans for Marriage Equality campaign.

“My husband and I are raising our daughter Birdie to live by the Golden Rule to treat others the way you wish to be treated. I feel like as Americans we should apply that to all aspects of life, including marriage,” Philipps says in the 30-second video released Thursday.

“Gay and lesbian couples just want the same rights that we all have, nothing more and nothing less,” she adds. (The video is embedded on this page. Visit our video library for more videos.)
