Mama June tells Dr. Phil -- The Child Molester Hotel Room Pic is Fake

Mama June did a sit-down with Dr. Phil Wednesday and claimed TMZ doctored the pic showing her in a hotel room with convicted child molester Mark McDaniel.

Phil gets heated with June ... calling her out on her allegation. As we reported, we were told June was sneaking away from the production of "Here Comes Honey Boo Boo" to have secret rendezvous with McDaniel.

June made a bunch of claims during the interview -- which will air Monday -- including TLC allegedly folding and paying her full salary for the cancelled season. As TMZ reported ... TLC sources told us they blamed June for the cancellation and decided to pay her only a portion of her pay.

Our TLC sources say June lied on Dr. Phil's show ... she did NOT get payment in full because of her misconduct.

BTW ... we didn't doctor the pic.
