America's Got Talent determined five more Top 20 fourth-season semifinalist acts during Wednesday night's live broadcast of the NBC reality competition series.

Hairo Torres, a contortionist breakdancer from Grants Pass, OR; Jeffrey Ou, a pianist from Carrollton, TX; Mario and Jenny Ferreira, a married juggling team from Las Vegas, NV; and Lawrence Beamen, a singer from Walnut Creek, CA were revealed to have finished as the Top 4 vote-getters after Tuesday night's performance show that featured the season's third group of 12 quarterfinalists performing for home viewer votes, automatically earning them a spot as Top 20 semifinalists.

America's Got Talent judge Piers Morgan described the home viewer voting results as "shocking."

"I think America's made some strange decisions with a couple of these acts," he said.

America's Got Talent host Nick Cannon also revealed that singers Marcus Terrell and the Serenades, musician Bri Bernstein, illusionist Jay Mattioli, comedian Dave Johnson, and girl band G-Force had received the six lowest home viewer vote totals and been eliminated from the competition.

The announcements then left Piers and his fellow America's Got Talent judges Sharon Osbourne and David Hasselhoff with the task of deciding which of the two acts that had received the fifth and sixth highest vote totals -- FootworKINGz, a dance ensemble from Chicago, IL, or Pixies Mystere, dance and contortionist group from Cape May, NJ -- should become the final Group 3 quarterfinalist act to advance to the semifinals.

"I love our little pixie magics.  I love you," Sharon said as she began to reveal her vote.  "However you are still children.  You're not even teenagers yet.  I really do feel like you have got so many more opportunities to come to you in your life.  But I think it's FootworKINGz time right now to stay and go on.  So Pixies, I'm going to have to send you home."

Piers called the decision between the FootworKINGz and Pixies Mystere as "very difficult."

"I'll tell you why," he continued. 

"I've got to my left the Pixies, who without any doubt are one of the most talented young group of dancers we've had.  And to my right, we have FootworKINGz, one of the most talented adult groups.  They're both in their own way exceptional talents.  But I have to go with the act I genuinely believe has the best chance of winning... That is FootworKINGz."

Since the FootworKINGz had already received two of the three judges' votes, David's vote did not carry any weight.  However he revealed his vote was also for the FootworKINGz.

"They rock, baby," said David.  "You deserve to be here."

America's Got Talent's next episode will air Tuesday, August 25 and feature the season's last remaining group of 12 quarterfinalists performing for the chance to advance to the semifinals.
