America's Got Talent revealed its last set of five ninth-season semifinalist acts during Wednesday night's live results show of the NBC reality competition series.

Emil and Dariel, a pair of cellists; Jonah Smith, a band of three male members; Quintavious Johnson, a 12-year-old singer from Franklin, TN; and Tomas "Smoothini" de la Cruz, a magician and comedian from New York City, were revealed to have finished as the Top 4 vote-getters after Tuesday night's performance show, automatically earning them a spot in America's Got Talent's ninth-season semifinals.

Tuesday night's episode had featured the season's fourth -- and final -- group of 12 quarterfinalist acts performing for home viewer votes.

America's Got Talent host Nick Cannon also revealed that circus performer Jonatan Riquelme, card-throwing triplets Dom the Bom's Triple Threat, Extreme Dance Company, contortionist Nina Burri, Bad Boys of Ballet, and aerialists Mothmen Dance had received the six lowest home viewer vote totals.

The announcements then left America's Got Talent judges Howie Mandel, Heidi Klum, Melanie "Mel B" Brown, and Howard Stern with the task of deciding which of the two acts that had received the fifth and sixth highest vote totals -- Kelli Glover, a singer from Cranford, NJ, and One Voice Children's Choir from Utah -- should become the fifth act to advance to the semifinals.

Mel B. voted to advance Kelli, Howard voted for Kelli and then Howie also cast his vote for Kelli, sealing the deal for the singer to move on to the semifinals. Heidi did not need to reveal her choice.

Now that the Top 20 has been determined, the judges still have to announce their four Wild Card picks. Once those Wild Cards are revealed, the season will feature a Top 24.
