Lady Gaga Tries to Go Home

This Sunday night at 7 p.m. ET/PT, right before the Grammy Awards, "60 Minutes" features an in-depth profile of "Lady Gaga," a 24-year-old pop star formerly known as Stefani Germanotta. Anderson Cooper talks with Gaga about her improbable rise from college drop-out to pop star, her philosophy on fame, and her new album.

In this excerpt, Lady Gaga finds out that it's not always easy to go home again when she takes Cooper and a "60 Minutes" camera crew to the apartment in New York where she lived before she became one of the most famous people on the planet.
