Chris Cuomo, the news reader on ABC’s Good Morning America, will reportedly be replaced by ABC News correspondent JuJu Chang. (The New York Post first reported the story.) The shake-up comes as the network re-works the show around Diane Sawyer’s departure this Friday to anchor World News. George Stephanopoulos has been offered Sawyer’s spot on GMA. ABC News had no further comment to EW, but several outlets are reporting that Cuomo could end up co-anchoring ABC’s Friday newsmagazine 20/20 with Elizabeth Vargas. The son of former New York governor Mario Cuomo wrote on his Twitter feed Monday morning, “Yes, change is coming…All is good. Will tell more soon.”

MTV’s Jersey Shore has lost a bit of advertising after concerns were raised over the reality series’ depiction of Italian-Americans. But Domino’s, which decided not to run ads on the show after appearing in one spot on the Dec. 3 premiere episode, says the decision wasn’t due to Italian-American organization UNICO National’s complaints. The pizza chain also says it will continue to buy time on the network, just not specifically on Jersey Shore: “Our third-party media buyer, after reviewing the show, told MTV Friday morning that the content wasn’t right for Domino’s,” a spokesman said. “The request to keep our spots from future episodes took place in the morning, well before we received any complaints or inquiries from anyone. We make our ad buy decisions internally, not due to any outside influences. We have no issue with MTV, and we haven’t pulled our advertising from the network. We just don’t want to be on that particular show.” American Family Insurance also stopped running spots during the controversial show, but for strictly technical reasons, a spokesman said: The company had “a very limited association” with the show, with promos for special safe-teen-driving webisodes running during the premiere, but set to end when the online series ended on Sunday. “The only action we took was to ask them not to run the promos during the Jersey Shore reruns this weekend,” the spokesman said.

Bryant Gumbel revealed that he has lung cancer while guest co-hosting this morning’s Live! With Regis & Kelly. The 61-year-old former Today show anchor said he’s being treated for the disease after surgery last month to remove a tumor from his chest. “We had told a few people, we told my family, obviously,” he said. “I even kept it from my staff at Real Sports. So I’m okay for the time being.”
