America's Got Talent aired its first semifinal show of the season Tuesday night, featuring twelve semifinalists competing for six slots in the top 12.

Here are some of the highlights from the night:

Collins Key:

This young magician performed a trick involving the audience and the judges, matching various features drawn at random to one select person in the audience. Though judge Howard Stern did not like his performance, Mel B and Mandel said that they loved it and praised his charisma.

Dave Fenley:

Fenley sang an acoustic cover of Say You'll Be There by the Spice Girls. Stern said that he hated the performance, but Mandel said that he was the best act of the night up to that point and stepped his act up. Mel B, who was a member of the Spice Girls, said she would "buy that song in a second."

Taylor Williamson:

This awkward comedian tailored his standup comedy to Klum after her comments in the quarterfinals about wanting him to be more family-friendly. Klum admitted that she thought he was funny and Mandel amended his comments, saying that Williamson was the best act of the night up to that point.

Cami Bradley:

Performing an acoustic version of Can't Help Falling in Love by Elvis Presley, Bradley touched the judges with her tender voice. Though Mel B wasn't as impressed, the three other judges said that she was great and deserved to advance to the top 12 round.

Forte:

This opera trio performed Unchained Melody by The Righteous Brothers. All four judges gave them a standing ovation, with Mel B saying she had finally come around to them. Mandel said that the trio had solidified a legitimate career after their performance.

America's Got Talent will air the results of Tuesday's show at 9 p.m. on Wednesday on NBC. The top 5 acts with the most votes will automatically be sent through to the top 12 and the judges will choose a sixth act to advance to the next round.
