Girl power ruled at the Sound Of Change concert in London, which Beyonce headlined.
The Girls On Top songstress, who showed off her curves in an embellished leather body suit, was joined by her rapper husband Jay-Z for a duet during her 45-minute set featuring versions of Run The World (Girls), Single Ladies (Put A Ring On It), Halo and the Destiny's Child classic Survivor.
"It's time for change. Let's chime for change. This is such an incredible night for me," said the 31-year-old after being introduced by the concert's co-founders Salma Hayek Pinault and Frida Giannini.
Music's hottest names including Jennifer Lopez, Rita Ora and Florence + The Machine, Ellie Goulding, Iggy Azalea and girl group Haim took to the stage at the star-studded show at Twickenham Stadium, along with John Legend, Timbaland and Duran Duran frontman Simon Le Bon.
Prince Harry opened the show with a video welcome before Jessie J, who donned a black sparkly crop top and black trousers, started the evening with Price Tag, followed by Nobody's Perfect. Lopez - who was joined by Mary J Blige for Come Together - wowed in an embellished body suit with strategically placed fringing, following her risque performance on ITV show Britain's Got Talent.
Madonna, Blake Lively and husband Ryan Reynolds, James Franco, Jessica Chastain, Freida Pinto and Zoe Saldana were presenters on the night. The fundraising gig, organised by the Gucci-founded charity Chime For Change, Salma Hayek Pinault and Beyonce, raised 4.3 million US dollars (around £2.8 million).
Ora said after her performance: "I loved every minute and the fact that I'm here for a cause I really believe in makes it 10 times better. I have my own separate charity for women, single mothers and children so it's just really important for me to be here."
Other stars paid tribute to their mothers as their inspirational role models. Oscar-nominated actress Chastain revealed: "My mother and my grandmother are my greatest teachers. One of my favourite films I've ever made was The Help, I love working with women so this is a great cause to be involved in."
Gossip Girl star Lively said: "My mum came from little to nothing. I've learnt by living by example. Her family has always been her first priority in life. The biggest thing I've learnt from her is she doesn't say no and that's why she has accomplished so much. It can be frustrating when I'm sharing dessert with her!"
Pinto added: "It's important for me to get involved because we want a society that is equal in terms of the education that goes to men and women. We want to be free of discrimination and we want a society that's changing for the better. My mother taught me that."
