DeGeneres discussed the controversy, which prompted aninternal investigationlast summer, in herTHRinterview, saying it “almost impacted the show.”

“Kelly Clarksonis a logical choice,” says an industry source of the singer, who hosts her own titular talk show on NBC.
The source adds that DeGeneres' exit was not a surprise: “She was almost out the door before the controversy. She’s been talking about leaving for a few years now, but that was definitely the last straw.”
