“Supergirl” star Nicole Maines discusses what it was like growing up transgender as she makes her first talk show appearance on “The Ellen DeGeneres Show” Tuesday.

The 21-year-old, who is TV’s first transgender superhero, opens up to DeGeneres about identifying as female from a very early age, telling the host: “I started thinking something wasn’t right at three or four years old.

“My case was kind of unique because I have an identical twin brother, so growing up with him he was identifying with all of these male things and he was feeling very comfortable in his body.”

Maines goes on to say when asked about how her parents reacted, “My father grew up very conservative, he had set expectations for what boys and girls were supposed to be like.

“When I came out to him that did not fit into his plan of what raising twin boys would be like. He blocked that out, ignored it, and that left my mother on her own for a while.”

However, she insists that her father immediately stepped up to protect her when her safety was at risk.

Maines’ interview also sees her talk about her new role in “Supergirl”, with the actress insisting she still can’t believe it’s finally happening. She plays Nia Nal, aka Dreamer, in the upcoming fourth season of the Showcase superhero drama.

She admits, “Everyday I walk on set and I’m waiting for someone to say ‘Ma’am, you can’t be here.'”
