Beyonce says that the thing that amazes her most about her mom is that she excels at "finding the best qualities in every human being." Several other celebs -- John Legend, Ziggy Marley, Cameron Diaz, Blake Lively and Olivia Wilde -- share their favorite things about their mothers just in time for Mother's Day. The video is part of Gucci's Chime for Change initiative that aims to raise awareness in women through powerful stories about inspirational females. Beyonce and Salma Hayek are among the committee's founding members. King Bey will also perform at the London Chime for Change concert on June 1 along with Legend, Florence and the Machine, Timbaland, Jennifer Lopez, Ellie Goulding, Haim, Iggy Azalea, Rita Ora and more.
