"We watched the show back and the final 12 we're very happy with," said Simon Cowell at the top of the show. "We think we made a mistake with one act."

With that, a thrilled White emerged telling the crowd it was "awesome" that the judges had a change of heart.

As for the performances, the now-13 acts tackled "movie week," with some of the performers playing homage to members of the judging panel.

Harking back to Spears' silver screen debut Crossroads, Jennel Garcia belted out I Love Rock 'n' Roll while Emblem3's Temptations/ Katy Perry mash-up incorporated a dash of One Direction's What Makes you Beautiful. The superstar Brits rose to fame under Simon Cowell's X Factor mentoring.

Speaking of, One Direction will drop by the show Thursday night to perform as the top 13 become 12.

The X Factor airs Wednesdays and Thursdays at 8 p.m. on FOX.
