American actress Ellen Page has come out as gay, saying she's "tired of hiding" and "tired of lying by omission."

With a slightly trembling voice, the "Juno" star delivered an impassioned speech on Valentine's Day in front of hundreds at the Human Rights Campaign Foundation "Time to Thrive" conference in Las Vegas.

"I'm here today because I am gay," Page said, pausing briefly after receiving a standing ovation from audience members. "And because maybe I can make a difference to help others have an easier and more hopeful time."

The 26-year-old thanked those in the conference crowd who work with and counsel LGBTQ teens for inspiring her to come out.

"I suffered for years because I was scared to be out," Page said. "My spirit suffered, my mental health suffered, and my relationship suffered.

"We deserve to experience love fully, equally, without shame and without compromise," she said.

After receiving an outpouring of public support, Page took to Twitter to thank her fans.
