"[I meant] no disrespect. Adam's a friend of mine," Jackson said of The Voice coach Adam Levine during an appearance on The Ellen DeGeneres show, Us Magazinereported Wednesday.
"I think The Voice is a great show."
Last month, Jackson had put down The Voice by calling it a "second chance" competition, using the show's first-season winner Javier Colon -- who was mentored by Levine throughout the season -- as his justification while speaking with reporters during a press panel about Idol's currently-airing eleventh season.
"The winner of The Voice, I will remind you, was an artist who had a deal at Capitol Records for several years, a failed contract," the Idol judge told reporters, according to Entertainment Weekly. "That show was almost 'second chance people.'"
"Shame on Randy Jackson for saying that because he, out of anybody, should know that if you're in this business you need second, third, fourth, and fifth chances. So we love and embrace that being part of the show," Levine said during an appearance with fellow The Voice coaches Blake Shelton and Christina Aguilera on DeGeneres' show earlier this month. "It was irresponsible for him to say that."
However, Jackson is taking back his slam and clarified what he meant by saying The Voice is a "second chance" reality singing competition.
"You can have as many [chances to succeed] as you want. I'm saying the difference is [that Idol features] new people," Jackson reportedly told DeGeneres, suggesting that the Fox series was the first show to discover fresh talent.
"Because the first thing that goes into my mind if you have had three or four [prior opportunities to make it in the industry] is that there is something that you're missing that you don't quite know yet. People have tried to discover you but it didn't happen."
