In the latest Chime For Change campaign video, co-founder Beyoncé Knowles-Carter is joined by Blake Lively, Cameron Diaz and Olivia Wilde in praising their mums ahead of Mother's Day in the US.
Bey is the co-founder and artistic director of the Gucci founded girls' and women's empowerment initiative alongside Salma Hayek and Gucci's Frida Giannini.
Other famous faces who have added their support to the campaign in the video include Halle Berry, Katy Perry, John Legend., Zoe Saldana, Freida Pinto, Jada Pinkett Smith and Evan Rachel Wood.
You must already know that Beyoncé is headlining the Chime For Change women's empowerment concert in London later this year.
As well as the names we've already died over, it was recently announced that Jennifer Lopez will be performing with James Franco, Blake Lively and Jada Pinkett Smith appearing as presenters as welll.
The London Twickenham Stadium gig will take place on 1 June 2013 and you can bag you tickets here.
