In addition to celebrating her cancer-free health, Good Morning America's Amy Robach, 45, is reveling in her promotion to co-host of 20/20. While she says she'll still appear two or three times a week on GMA (which recently announced it will add a third hour in the fall), she's already seen her new office, which once belonged to legendary newswoman Barbara Walters!

"I have to tell you, I started to cry," Amy exclusively tells Closer Weekly. "That is a dream, that is the pinnacle of my career and so I am beyond honored to have this job."

"I want to live up to the standards that Barbara created when she began 20/20," she tells Closer. So has Barbara offered her any advice? "You don't have to ask for advice," Amy says with a laugh. "She tells you! She is just all about keeping it real, and you have to connect, connect, connect with people."
