"I used to wish for twins, and then I finally had a child, and I go, [that's] crazy," Perry said, shaking her head in faux-shock.
They then dropped the bomb that they are the oldest of eight children, and Perry looked mortified.
However, the siblings clearly have a connection as they went on to blow the judges away with an original song that earned them some high praise -- as well as two tickets to Hollywood!
Later in the episode, Perry came face to face with Hannah Everhart from Canton, Mississippi -- a near lookalike of the "Roar" singer.
"Are you the country version of me?" Perry asks, putting on a fake deep south accent.
"Everybody says I look like you," the quiet and reserved Everhart confirmed.
The nervous songstress started off with a performance of Johnny Cash's "Wayfaring Stranger," during which she showed undeniable talent, but was clearly uncomfortable in front of the judges.
She later admitted she originally wanted to sing "At Last" by Etta James, but decided to "play it safe."
This was enough to spark a fire in Perry, and she pushed Everhart to give them a taste of "At Last." After a few nervous bars, Perry got up and sang some herself, encouraging her to try and match her vocals.
"You are no longer allowed to play it safe," Perry said, after her impressive second number. "You better start rolling the dice on your life."
Despite the few hiccups, and Everhart's tough-as-nails exterior, the trio all voted to send her to Hollywood, making Everhart a real wildcard contender for the season.
