Canadian actress Ellen Page has announced that she is gay.

The 26-year-old Juno actress talked about her sexual orientation at the Human Rights Campaign's Time To THRIVE conference for LGBTQ (Lesbian, Gay, Bisexual, Transgender, Questioning) youth in Las Vegas.

"I'm here today because I am gay," Page told the crowd. "And because maybe I can make a difference. To help others have an easier and more hopeful time. Regardless, for me, I feel a personal obligation and a social responsibility."

She also mentioned in her speech other celebrities such as football player Michael Sam, Orange Is the New Black star Laverne Cox and lesbian identical twin musicians Tegan and Sara Quinn who showed the courage to come out and reveal their sexuality.
