The annual celebration - which is observed globally - was
founded in 1988 by two gay advocates in the United States.
The date of October 11 was chosen because it was the anniversary
of the 1987 National March on Washington for Lesbian and Gay
Rights.
Speaking to DIVA, Peace said: "I've been out to family, friends
and colleagues since my early twenties, but when I accepted my role
in Lip Service I felt like I also accepted a responsibility to be a
visible role model for other young gay people.
"This was the best and most fulfilling decision I've ever made. My
music career has benefitted hugely, I love my job on Lip Service
and I'm currently filming the new series of a mainstream BBC 1 TV
show.
She also added that coming out enabled other people, including
fans, to reach out and offer their support.
"But better than this, I get Tweets, emails and Facebook messages
every day from gay people of all ages who tell me that seeing me
live my life openly has helped them come out or helped their
friends or family understand a little bit better," she said.
"So, happy National Coming Out Day everyone, I recommend it."
