Cyndi Lauper is the latest celebrity to join the Human Rights Campaign's (HRC) New Yorkers for Marriage Equality campaign.

“It's time for our state to be a leader in the fight for fairness,” Lauper says in her 30-second video ad released on Tuesday.

“Besides, what business do we have telling other people who they can marry and who they can't,” the singer adds. (The video is embedded in the right panel of this page.)

The 57-year-old Lauper is a strong advocate for gay rights. Her True Colors Fund raises awareness and funds for gay rights causes. Later this year, the group is expected to open in Harlem the True Color Residence, a permanent housing development for LGBT homeless youth.

Lauper is among the growing list of celebrities, professional athletes and prominent politicians to record a video for the campaign that began last year.

The prospects that New York would become the sixth state to legalize gay marriage brightened considerably on Monday when proponents picked up the endorsements of four previously undecided state Senators. Later in the day, a fifth previously undecided senator, Roy McDonald, announced he'll back the measure.
