ET's Mary Hart sits down Jon Gosselin in an all-new interview -- and TV's most controversial dad shoots down claims made by his estranged wife Kate that he withdrew more than $200,000 from their joint bank account.

"I have the proof right here that I only took $22,000, which is my paycheck," Jon reveals to Mary.

The dad of eight says it's "absolutely not" true that he has made it difficult for Kate to pay her bills -- going on to claim that she has 11 bank accounts and made $1 million from her book.

Also in the revealing interview, a visibly-tense Jon tells Mary that he has been locked out of a room that holds important records, saying, "banking, financial, safe, everything is in that room. My clothes are in that room. I just want access to that stuff."

Watch the video to hear Jon's side of the story -- including whether or not his kids were moved to tears when they heard that Jon was trying to stop production of their TLC show.
