For Mother's Day 2013, Beyonce gathered a slew of celebrities to talk about what their mothers mean to them. As part of her organization, Chime for Change -- which acts to empower and promote girls' and women's issues worldwide -- Beyonce asked Cameron Diaz, John Legend, Ziggy Marley, Olivia Wilde, Blake Lively and Hafsat Abiola to reveal what makes their mothers unique.

"To me, she's the greatest celebrity I've ever met," says Lively at the beginning of the video.
Marley continues: "She's a strong woman who leads by example."
Beyonce: "Her gift is finding the best qualities in every human being."
Diaz: "Somehow she would have a thousand balls up in the air at one time and be able to catch all of them."
Wilde: "She is a true revolutionary."
Abiola: "I still remember what she taught me, I still remember her values."

The video ends with ends with each artist announcing their mother's name.

"Our goal is to call for change for girls and women in the loudest voice possible," said Beyonce of her organization. This will be her second year celebrating mother's day as a mother herself, as her daughter Blue Ivy was born January 2012.
