American Idol may be over forever , but the decade-long tension between original Idol Kelly Clarkson and highest-earning Idol Carrie Underwood seems like it will never end! RadarOnline.com has exclusively learned that – at last night's finale taping – the 33-year-old blonde country superstar "threw a fit" over Clarkson's performance backstage! Click through seven epic behind the scenes photos inside the last Idol cat fight ever!
Season four Idol winner Underwood – who is the highest earning Idol of all time with a net worth of $75 million – belted out a duet last night with longtime Idol judge and friend, Keith Urban, 48.
But according to a production source on the hit show – which ended its 15-year-run on Fox this season – "a duet was not what Carrie wanted!"
"Carrie caused serious drama with the final production of the show because she flipped out that she was stuck doing a duet when she has a tour and so many things to promote right now," the insider claimed.
"Carrie wanted to perform on her own, and the producers knew that," said source.
Underwood's eight-year grudge against Clarkson, 33 – who was the first to win the singing competition show in 2002, yet has a net worth of $24 million less than Underwood – took a nasty turn last night when Clarkson was given an entire segment of the show to do a medley of her greatest hits!

"Carrie said she just felt like she should have gotten the same type of treatment that Kelly did since she is the big money-maker from the show," the source told Radar. Underwood's rep did not immediately respond to Radar's request for comment.
