Jermaine Jones, who Ryan Seacrest referred to as 'the gentle giant', was let go from the Fox show Wednesday night.
Nearly an hour and a half into the two hour show, Seacrest announced that Jones allegedly concealed his criminal past from the show's producers.
"November of last year, you were criminally charged and gave them a fake name. You didn't disclose those charges to us," said executive producer Nigel Lythgoe.
"There are four active warrants out for you," said "Idol" producer Ken Warwicke.
"When I spoke with him, I said, 'You've gotten a lot of criticism about being a mama's boy, explain that,'" she said.
"I'm okay with it because my mom, she always has my back," said Jones. "She's always been there for me. She wants the best for me. She loves me and that's my support system, so I don't mind throwing it out, and giving her love right back."
By the time Wednesday's "American Idol" broadcast hit the air, Jones had already left Los Angeles. He was spotted in an airport in Philadelphia apparently heading home to New Jersey.
