'American Idol' Top 13 :Wild Card Winners!

"American Idol" went wild Thursday night as three of the eight wild-card hopefuls made it into the Top 12 -- but in a shocking, last-minute turn of events, the judges allowed a fourth contestant through.Jasmine Murray, Megan Corkrey and Matt Giraud became the final three singers to get the judges' blessing -- that is, until Simon told Anoop Desai right before the show went off the air: "We decided recently we're going to make this a Top 13."

So, this season it will be Jasmine, Megan, Matt and Anoop joining Lil Rounds, Scott MacIntyre, Jorge Nuñez, Alexis Grace, Michael Sarver, Danny Gokey, Allison Iraheta, Kris Allen and Adam Lambert in the Top 13.

Thursday night's wild-card round concluded with one of the most dramatic last-second turn-arounds in the show's history -- a decision to expand the final group from 12 to 13 to accommodate UNC-Chapel Hill student Desai. Earlier in the show, he performed Bobby Brown's "My Prerogative," earning generally positive marks from the judges.

"You slayed it," Randy Jackson said, although fellow judge Simon Cowell was more measured."You're like an enthusiastic dog," Cowell said. "Not the best singer we'll hear, but people like you."After his performance, Desai got in a shout-out to his hometown and the memory of Eve Carson, the late student-body president who was murdered a year ago today.

"It's been a tough day, we're all thinking of Eve and I love you, Chapel Hill," Desai said.As the judges announced their decisions at the end of the show, Desai was pitted against Matt Giraud for the 12th and final spot. Giraud was awarded the last spot, until Cowell announced that the final group would be a top-13 this year.
