Miss New York Claire Buffie is the latest celebrity to join the Human Rights Campaign's (HRC) New Yorkers for Marriage Equality campaign.

“I believe that everyone, including my sister Sarah, deserves the right to marry the one they love,” Buffie says in her 30-second video ad released Friday. “That's why I'm a New Yorker for marriage equality.”

“I competed in Miss America 2010 on an LGBT rights platform because this is a fundamental fight for fairness,” she adds. (The video is embedded in the right panel of this page.)

The 24-year-old beauty queen is the first to use the Miss America platform to champion gay rights. She's also an executive board member of the gay rights group Parents, Families and Friends of Lesbians and Gays (PFLAG).

Buffie is among the growing number of celebrities and prominent politicians to record a video for the campaign that began last year.

Five gay rights groups – including HRC – last month announced the formation of New Yorkers United for Marriage to begin a new push for the legalization of gay marriage in New York. The campaign is being coordinated out of Governor Andrew Cuomo's office.

Former President Bill Clinton and his daughter Chelsea Clinton have also thrown their support behind New York's latest effort to legalize gay marriage.

A Gallup poll released on Friday found 53% of Americans support marriage equality.
