Victoria Beckham [1] is one of Glamour's 2015 Women of the Year [2], and today the designer linked up with the magazine's editor in chief, Cindi Leive, for an interview on Good Morning America. Since she's being honored for her work as a designer and philanthropist, Victoria reflected on her influential position. "It took me getting to 40 years old to realize I have a powerful voice," she said. "People will listen to what I say, for whatever reason." Victoria also spoke about the challenges of being a working mother and revealed one piece of invaluable advice she once received from Diane von Furstenberg.
