Trailer Flowersare singing their hearts out, no matter what their critics think.

During Tuesday’sAmerica’s Got Talentlive show,Howie Mandelsneakily pressed fellow judgeHeidi Klum’s red “X” buzzer as the country duo performed their original song, “Who You Are,” on stage.

Despite Heidi calling him out andcameras actually catching himdo the deed, the 67-year-old judge insisted he “would not press my buzzer in the semifinals.”

Simon Cowellalso addressed the matter, offering an apology to the Nashville singers. “First of all, I don’t think the producers should have done what they just did, because we don’t have a lot of time to talk and actually give you something constructive,” he said of the producers replaying the moment on screen. “So I apologize.”

“We don’t live for anyone’s criticism, and so I honestly had open hands about whatever the judges may have to say,” Brooke tells PEOPLE. “We respect anyone’s opinion, and it’s okay if we’re not for everybody. So we’re excited to spread country music and to keep doing our thing.”

Jack echoed her partner’s words, sharing, “We don’t live for anybody else’s validation other than Jesus Christ.”
