"Kelly is a doer, a pusher, someone who forges ahead even when it's difficult for her," says an insider. "Being busy is a blessing and she knows that." Working on her NBC daytime talk show and gearing up for the new season of The Voice, the star is also still working on her upcoming album. "Music builds her up even if her songs are confronting her troubles," says a friend. "Kelly will come out of this a stronger person." Last week, Clarkson, 38, picked up her first Emmy award for outstanding entertainment talk show host and publicly thanked her music manager ex on Twitter. While some fans expressed surprise at her comment, sources say the gesture wasn't unexpected. "Brandon's confidence in her talent and his ability to push the right buttons for her has been great for her career," says the friend. "Kelly's excited, proud and grateful." On Saturday, the singer took part in a telethon for Project Angel Food, a Los Angeles-based organization that cooks and delivers healthy meals for those in need.
