Lady Gaga's is 'doing unbelievable' after surgery

Lady Gaga's manager says the pop star is "doing unbelievable" a month after she had hip surgery that caused her to cancel her U.S. tour, The Associated Press reports. Vincent Herbert said in an interview that the Grammy winner is "doing wonderful, doing great." Gaga, 26, whose real name is Stefani Germanotta, canceled her "Born This Way Ball" tour last month. Herbert says Gaga is finishing her new album, "ARTPOP," and is "ready to get back to work."
