Kelly Clarkson has boasted she never needs to work again.The first 'American Idol' winner - who fired her manager Jeff Kwatinetz last month - claims she was rich enough to retire two years ago. Kelly, 25, bragged to Reader's Digest magazine: "I have saved and saved, and I don't have to work another day."When I won 'Idol' and started working with a business manager, she asked,'What do you want?' I told her I don't ever want to have to make a decision because I need money. So we accomplished that two years ago, and I'm set."The 'Miss Independent' singer recently fell out with 75-year-old Clive Davis, the Chief Executive of her record label RCA, because he didn't like the songs she had chosen for her latest album 'My December'.Kelly said: "I just want people to hear it, instead of 100-year old executives making decisions on what's good for pop radio. It's people my age who listen to it. My gut hasn't been wrong yet, so why wouldn't I continue to follow it?"They hated 'Miss Independent' on my first album. It was number one for six weeks, then they got behind it."They hated 'Breakaway'. The song I wrote that they hated the most was 'Because of You'. I fought and fought for it, it became successful and they finally got behind it. I'm not complaining, I'll just say no until I get my way, and I did."
