The feud started when Jackson made some choice comments about "The Voice's" Season 1 winner Javier Colon and his record deal that was in place before his time on the NBC reality series.
"'Idol' is still the best TV show that's come on anywhere ... We're the original. We kind of invented this whole game that everybody's now copying -- and I say that they're copying it, right? ... The winner of 'The Voice,' I will remind you, [Javier Colon] was an artist who had a deal at Capitol Records for several years, a failed contract … That show was almost 'second chance people,'" Jackson said at the TCA press tour.
"The Voice" judges shot back when they stopped by DeGeneres' show. "Shame on Randy Jackson for saying that,” Adam Levine told DeGeneres. "Because he of anybody should know that if you’re in this business you need second, third, fourth and fifth chances. So we love and embrace having that being part of the show."
Jackson told DeGeneres it's "all love" between him and Levine. The two have hung out with "American Idol" host Ryan Seacrest "a trillion times."
"I think 'The Voice' is a great show, I think what they do is great." Jackson said. "I was just saying that the kid [Colon], I actually worked with ... The premise of our show -- what I was really trying to say -- we're about finding the next undiscovered talent, the greatest undiscovered talent in America."
