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.”
