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.
