Jermaine Jones was kicked off the show before Wednesday night's episode.
Viewers were shown a taped section where producers Ken Warwick and Nigel Lythgoe confronted him about the issue.
"You were incumbent to tell us the truth about all of this, and it appears that you just haven't on any level," Ken Warwick told Jones.
The 25-year-old vocal instructor from New Jersey was one 13 finalists chosen by viewers.
The judges - Jennifer Lopez, Randy Jackson and Steven Tyler - had given him a last-minute spot in the male semi-final.
He was in the bottom three last week after performing Stevie Wonder's Knocks Me Off My Feet but managed to get through to the final 12.
"I didn't want to get judged," said Jones. "I didn't want to get penalized for anything that happened in the past."
Host Ryan Seacrest said the remaining 11 finalists would be "at risk" of being eliminated on Thursday (15 March).
Joanna Pacitti was disqualified during season eight in 2009 and Chris Golightly was kicked off the show during season nine, although no official reasons were given.
