Surgery helped Aretha Franklin lose 85 lbs. – just not that surgery.

That’s the story the Queen of Soul’s sticking to as she once again shoots down rumors about her health, this time the theory that she underwent gastric bypass surgery to drop weight.

“Definitely not – and would not,” Franklin, 68, tells Access Hollywood in a two-part interview to air Monday and Tuesday. “I heard that [rumor]. I said, ‘That is crazy.’ ”

Since undergoing a mysterious surgical procedure in December for reasons she refuses to reveal, Franklin’s health and weight loss have been much-buzzed-about topics. In January, she said she was “not going to even deal with” rumors that she had pancreatic cancer.

She did, however, offer a small clue about that surgery, saying that the weight came off “from the surgery that I had,” although she did not specify the procedure.
