Juliet Evancho: Who Is America's Got Talent Star Jackie Evancho's Sister?

Like many talent-based reality shows, "America's Got Talent" has done much to promote entertainers' careers since its 2006 premiere, regardless of whether they won. From "Saturday Night Live" alum Melissa Villaseñor's impressions in Season 6 to dance crew Jabbawockeez in Season 2, the show has introduced many talented acts to the world. Among the most successful and well-known "AGT" performers is the little girl with the "angelic" voice: Jackie Evancho.

Evancho was only 10 when she took second place on Season 5 of "America's Got Talent" in 2010. She sang an opera aria that Piers Morgan called "one of the most extraordinary performances I've ever seen on 'America's Got Talent.'" He also asked the child, "Are you sure you're not 30?" Her overly mature voice had already caught the eye of music mogul David Foster, who later produced her 2011 album "Dream with Me." Her record deal set new heights, as Evancho became the youngest artist to debut on Billboard's Top 10, and her "O Holy Night" album made her the youngest solo artist with a platinum album.

Evancho is now 22, and of the utmost importance to her is her family. "I will never turn my back on my family, no matter what," she told ABC News. That particularly applies to her sister, Juliet Evancho, especially when a conflict between her career and her sister took center stage. But who is Jackie's sister, Juliet?

"I actually wanted to be a singer before Jackie did," Juliet Evancho confided to Nightline reporter Juju Chang. And Juliet performed and recorded with her sister Jackie, notably on the song "I See the Light." But Juliet is not the same person now as when she sang that song at age 13.

"I'm here to tell you that you don't have to sacrifice who you are in order to be loved and accepted," Juliet wrote in an op-ed for Teen Vogue. "On my 17th birthday my life finally began." Juliet used that 2015 birthday to reveal to her family that she was transgender. Assigned male at birth, Juliet always knew she was a girl. "I can remember talking to my mom about my feelings," she wrote. "I told her I don't think I'm gay — there's more to it than that. I feel like I really am a girl." At only 11, she recognized she was "a girl trapped in a boy's body."

Now, Juliet is a model represented by CC3 Entertainment. She walked in the dapperQ show at New York Fashion Week and has frequently shared photos on her Instagram page. She also uses her platform to fight for transgender rights, and her modeling is a big part of that. "I'm not your average cut-mold model," she told The Cut. "Obviously everyone knows I'm transgender, so I see modeling as a way to show people that trans people are in every industry, they're doing their jobs — they're people, too."

Fortunately, Juliet Evancho's family was supportive when she came out, though it took some time, especially for her father. "Juliet was always Juliet, and it was me saying, you know, 'oh, it's a phase,'" her father, Mike Evancho, told Nightline. "Now I realize that that was not the case." But the siblings always have each other's backs, and Jackie captured Juliet's story in the beautiful video for her Ed Sheeran cover "All of the Stars." Juliet even supported Jackie when she made a big mistake at Juliet's expense: Jackie faced criticism for performing at Donald Trump's inauguration.

"I supported Jackie through the whole thing," Juliet told Build, recognizing that it was a big career opportunity for her sister. "Jackie had already said the way she looked at it was she's singing for her country; she's not just singing for one man." After the inauguration, Jackie made a statement against the Trump Administration's anti-LGBTQ+ policies, which drew hate from his supporters. But the apolitical singer knew that speaking out was important. "I want everyone to be happy and feel equal," Jackie told ABC News.

Juliet's activism won a lawsuit against her Pennsylvania school district after they caved to pressure from anti-LGBTQ groups to adopt a discriminatory bathroom policy. Juliet told Nightline why the bathroom issue is so important. "Being able to walk into a women's restroom without thinking about it is kind of empowering in a sense because we get to be us in the most mundane ways."
