Out singer and Broadway performer Brian Justin Crum wowed the judges and earned a standing ovation last night on America's Got Talent, where he moved on to the next round of auditions after belting a heartbreaking rendition of Queen's "Somebody To Love."

In an introduction video before he took the stage, Crum talked about being bullied when he was younger for being overweight and gay, and how it helped forge a strong relationship with his mother.

"My mom being here is everything to me," Crum told the judges, with tears in his eyes. "I had a lot of hard times when I was a kid and she's been a huge supporter for me."

He added: "I hope that this is my moment to say thank you to my mom, and that I love you so much."

After his beautiful performance, which even stirred a positive reaction from the oft-critical Simon Cowell, Crum received rave reviews from all four judges.

"I'm guessing that's probably one of the biggest performances you've ever given — every ounce of you came out," said Cowell. The truth is you are a fantastic singer. This is why these shows exist, is to give people like you with huge talent an opportunity."
