Actress Sara Ramirez on Saturday revealed for the first time publicly that she's bisexual.

“So many of our youth experiencing homelessness are youth whose lives touch on many intersections, whether they be gender identity, gender expression, race, class, sexual orientation, religion, citizenship status,” Ramirez told a crowd at the True Colors Fund's 40 to None Summit in Los Angeles.

“Because of the intersections that exist in my own life: Woman, multi-racial woman, woman of color, queer, bisexual, Mexican-Irish American, immigrant, and raised by families heavily rooted in Catholicism on both my Mexican & Irish sides, I am deeply invested in projects that allow our youth's voices to be heard, and that support our youth in owning their own complex narratives so that we can show up for them in the ways they need us to,” she added.

The 41-year-old Ramirez is best known for playing Dr. Callie Torres on the ABC medical drama Grey's Anatomy. She won a Tony for her portrayal of the Lady of the Lake in the 2005 Broadway musical Spamalot.

Ramirez, who is married to husband Ryan DeBolt, has kept quiet about her sexuality despite playing a bisexual woman who eventually married a woman on Grey's Anatomy for 10 years.
