Newly crowned American Idol
Phillip Phillips is in no short supply of adoring female fans, but the Georgia native only has one of them on his mind – his girlfriend.
Phillips's brunette beauty was first revealed to the public by host Ryan Seacrest
just a few weeks ago, but the new winner says she has been his biggest cheerleader all season.
"She is so excited for me," the Leesburg, Ga., musician, 21, told PEOPLE during a conference call Thursday. "She supported me throughout all of this, and I love her to death."
Little is known about Phillips's girlfriend (her name remains unconfirmed), but he has said she is studying to be a nurse – which could come in handy, given that the singer has suffered kidney problems
throughout the season.
"She has helped me out a lot through this," said Phillips, who will undergo surgery "pretty soon" and wishes to leave his health problems behind him before he heads out on tour with the Top 12 this summer.
"I'm hoping maybe she will be able to come on tour with me," he said. "It would be cool to have her there."
While Phillips's being off the market may disappoint some of his admirers, the good-looking guitarist-singer hopes they will still remain fans of his music.
"If a girl [voted] for me because I'm cute, and then gets mad that I have a girlfriend, then she doesn't really like the music," he said. "I'm not some cute guy who is trying to be successful off that. I really want the music to come first."
