"Yes, that was my first inkling that something was wrong, that something wasn't what it should be," Franklin, 68, tells her.
"The pain was so hard it nearly brought me to my knees," the Queen of Soul continues. "So I said, 'The concerts are over. I have to go find out what is wrong.'"
"In December we all found out that you were having abdominal surgery," Williams says.
"Hmm," Franklin pauses. "Is that what you heard?"
(After reports surfaced that the singer was suffering from pancreatic cancer, Franklin squashed the rumors in an interview with Access Hollywood in January.)
