Jermaine Jones VS. 'American Idol' Producers -- The Confrontation [Video]

Jermaine Jones got a swift kick in the ass from reality last night ... when 'Idol' producers confronted the singer on tape and told him he's FIRED from the show for lying about his criminal past.

Jones took it well ... thanking executive producers Nigel Lythgoe and Ken Warwick for the opportunity ... and then getting into the back of a waiting car ... not a cop car.

TMZ broke the story ... Jones has 4 warrants out for his arrest and a history of allegedly using multiple fake names with cops.
