After last Wednesday's surgery to remove kidney stones that were too large to pass, the American Idol winner is ready to move on.
"I'm out of the hospital and back to work!" the Georgia-bred heartthrob, 21, tells E! News. "Looking forward to the future."
Phillips, who won over Jessica Sanchez in last month's emotional Idol finale, suffered throughout this season's competition.
His father, also named Phillip Phillips, said his son underwent eight operations during the course of the season. This last one took six and a half hours.
Phillips was released from the hospital in Los Angeles on Sunday afternoon, says E!
After some rest, the singer faces a heavy summer schedule that includes 45 shows. July 6, he's due to open the American Idols Live concert in Detroit, along with the season's top 10 contestants.
