ET caught up with the 28-year-old actress at the Freeheld
premiere in New York City on Monday, when she explained why going public with her relationship
with the surfer/artist is "so special."
"So far, that's not something I've experienced in my life," Page said. "And to love someone openly, to hold someone's hand walking down the street, it's a beautiful, beautiful, beautiful thing, and I'm just lucky enough to have someone in my life as special as her."
Page actually made her red carpet debut with Thomas
on Sept. 13 at the Toronto International Film Festival. Since then, the actress hasn't been shy about sharing photos of her significant other on Instagram.
She's also definitely flourished both professionally and personally since coming out last February
. Page is accepting the National Vanguard Award from the Human Rights Campaign on Oct. 3 in Washington, D.C., which will be presented to her by Vice President Joe Biden. The Inception
star has been outspoken in advocating for LGBT rights
"Really, I just feel so fortunate, you know?" Page said about her incredible year so far. "I feel so happy. I feel so different from how I felt when I was closeted, and to have experiences where I meet people who have been touched in some way by just getting to be who I am is such an incredible experience ... I'm in a very fortunate place in my life."
"I'm a very privileged person to get to talk about issues, particularly those that affect people much, much more vulnerable to me," she added. "I feel really grateful to be in a position where potentially I can do little things or whatever I possibly can to help anyone any way I can."
