The young singer got overwhelming love and support following her cover of Sara Bareilles' 'Gravity' on Tuesday.
Angelina Green is bringing a lot of emotion to the America's Got Talent live quarter-finals.
Weeks after Green earned the coveted Golden Buzzer from Heidi Klum during the AGT audition rounds, the 13-year-old singer stepped out onto stage again during Tuesday's live show at the Dolby Theater in Hollywood, and delivered another deeply touching performance that stunned the judges.
Green let her big, dynamic voice shine through with a touching cover of Sara Bareilles' "Gravity" that showcased her range, and the young songstress flawlessly nailed the soulful ballad's high notes.
Klum was the first judge to share her thoughts on Green's performance, and she said her faith in Green during the audition rounds had been well-rewarded.
"I want you to know I stand 100 percent behind you. You make me so very proud," Klum shared. "We have a lot of singers on the show, but you don't always recognize their voice. I do believe you have a very, very special and very recognizable voice, so you should be very proud of what you've just done."
As for Simon Cowell, the often acerbic judge had nothing but praise for Green, and said her voice was wonderful, independent of her age.
"It doesn't matter if you're 13, 23, 33, you just have an amazing voice," Cowell shared. "The biggest compliment I can pay you is, when I was listening to the song, I believed it was your song, and you weren't singing somebody else's song."
Mel B was equally effusive, telling Green, "I think that music is everything and it really speaks to people, and what you just did then is going to speak to everyone. You are amazing."
The young AGT hopeful got emotional during the judges' comments and couldn't hold back her raw excitement when host Tyra Banks asked how she felt about the supportive feedback.
"It's always been a dream for me to perform here, and it's coming true. I swear to you, I can't believe it," Green said through tears.
ET caught up with Green after the show, where she opened up about her performance and how she managed her nerves.
"Before the show, I knew that I was going to get nervous, so I did a little crazy dance," Green recalled. "But when I was actually on stage, I was just trying to take deep breaths and count to 10 and release."
Despite her dancing and breathing techniques, Green said the pressure of the live show and the huge audience still got to her a little when she stepped out on stage.
"I saw all the people and I was like, 'Oh my god!' It was so crazy! It was literally full!" she shared. "And to sing in front of those judges? I was like, 'Ahhh!'"
Ultimately, Green got over her nervousness and lost herself in the emotion of her performance, which allowed her to convey its significance to the judges.
"When I was singing, I was really trying to like, feel everything and Mel B started crying so it was like, 'Oh my god.' I couldn't believe it," Green said. "I literally transmitted my emotions to her, so I was really happy."
While she certainly lived up to the pressure nearly all Golden Buzzer winners feel, Green said she's "still super anxious" for Wednesday's live results show, where the 12 contestants who competed on Tuesday will get pared down to just seven, meaning five will be sent home.
"I really hope that America votes for me, because I'm super excited for the next round if I go through," she shared. "I'm going to give my best performance yet."
As the young singer explained during the audition rounds earlier this season, her love for music--and her ability to sing with real passion and heartache, came from a very tumultuous experience in her life.
"When I was little, one day my dad just left and he never came back," Green shared. "We were left with nothing. We would get eviction notices. I remember overhearing my mom on the phone with the homeless shelters. She was afraid we would end up on the streets, and it was just really scary for us. That’s when music helped me. It was my own little world that I could go to whenever I needed," she continued "I would sing and all my sadness and troubles, they would all go away."
To see if Green makes it into the semi-finals, tune in to the America's Got Talent results show on Wednesday at 8 p.m. ET/PT on NBC.
