“America’s Next Top Model” could be swapping one diva for one much tougher. Sources close to the catwalk competition say Vogue editor-at-large André Leon Talley will exit Tyra Banks’ series after its 17th season wraps, and Kelly Cutrone may take his place. Talley has been a judge for four seasons, including the current “all-star” cycle. He joined when Paulina Porizkova left. Cutrone, the tough-talking head of fashion firm People’s Revolution, appeared on MTV’s “The Hills” before starring in its spinoff, “The City,” and Bravo’s “Kell on Earth,” which she also executive produced. Reps for Cutrone, Talley and the CW did not respond to requests for comment.
