For their final feat, a blindfolded Tyce tried to catch Mary by the ankles - but she slipped through his hands and fell to the floor below.
When Mary got up she smiled and waved, and Tyce joined her on the stage to give her a kiss.
A husband and wife duo's terrifying trapeze performance went terribly wrong on America's Got Talent.
The accident was made more horrifying by the fact that Mary's mother and their 2-year-old son, Jaxx, were watching from the audience.
The couple progressed to the next round, with the judges recognising their skill, despite the fumble in their act.
Thankfully, Mary hopped back up unharmed, and the judges were sympathetic.
"This is not America's Got Perfection, it's America's Got Talent, nobody can do this", he consoled the couple.
Simon Cowell and co-judge Mel B were also left horrified by the whole event and were forced to look away in disbelief, while audience screamed and gasped in shock. He also pointed out how "incredible" it was that Tyce was able to do the performance even though he is almost blind.
"I don't think there's been a singer on any of our competitions who's been note flawless", Cowell said. "I mean, it's OK".
The embarrassed couple asked if they could do a repeat performance to make up for their slip-up. It still doesn't make them not unbelievable.
America's Got Talent returns for its second night of Judge Cuts next Tuesday at 8 p.m. ET/PT on NBC.
While the pair were understandably concerned that their mishap could spell the end of their AGT journey, they were overwhelmed when they were told they'd be moving on to the live rounds at the Dolby Theater in Hollywood.More news: US officials react to summit between Pres. Trump and Putin
