Rita Ora and Jessie J kick off star-studded Sound Of Change concert as they bare their midriffs on stage in cropped tops
It's one of the most star studded concerts of the year with a stellar line-up including Beyonce, Jennifer Lopez and Ellie Goulding.
So the stars taking to the stage for Chime For Change's Sound Of Change concert were of course battling for attention as they showed off their stage outfits and gave it their all on Saturday evening.
And it was Brit singers Jessie J and Rita Ora who kicked off proceedings to dramatic effect.
Kicking it all off: Jessie J and Rita Ora both bare their midriffs as they take to the stage for the Sound Of Change concert at Twickenham Stadium on Saturday evening
Crowd pleaser: Jessie was the first on stage and even treated her fans to a first performance of her new single, Wild
Jessie was the first on stage, showing off her bleach blonde shaved hairdo as she writhed around in a black cropped top and trousers.
She took the opportunity to treat the crowd to a first listen of her new single Wild.
It certainly seemed to have worked as the audience did indeed go wild as the impressive show kicked off at Twickenham Stadium.
Flashing the flesh: Rita Ora also opted for a black cropped top with shiny trousers as she took her turn to rock out on stage
Giving it her all: Rita stunned as she writhed around to her music in the stand out get-up at on Saturday evening
Making her marl: Rita was one of the early performers, kicking off proceedings for the rest of the night
Enjoying herself: Jessie J oozed confidence as she set the pace and mood for the night
And it seems crop tops were the uniform of the evening as Rita Ora, the second big artist on stage, also rocked out in a tiny midriff baring top.
Rita gave an energetic performance as she gave the stage some glitter in her gold sequin outfit.
She completed her look with a slick of red lipstick as she jumped up and down to her music.

She's no shrinking violet: Rita even sat down on the stage steps and lay herself out in front of the fans
An energetic display: The Kosovon-born singer was performing to a crowd of thousands, with the concert set to be streamed to an estimated audience of one billion worldwide
In between their two acts the stunned crowd were treated to a video message from Prince Harry, before actress Salma Hayek walked on stage in her glamour gown to introduce the proceedings.
The next big names to walk on stage were James Franco, who received a rapturous response from the audience.
He was flanked by Jessica Chastain before they introduced Rita on stage.
Following Ora's stand out set, Florence Welch was next to perform, although one of the biggest responses of the evening came when Madonna walked out.

Also performing at the charity concert was Australian star Iggy Azalea, who took to the stage in thigh-high boots and an eye-wateringly short skater dress, while Florence and the Machine singer Florence Welch opted for an altogether more conservative ensemble in a billowing teal fishtail gown.
The concert is part of Gucci's new global campaign for girls' and women's empowerment, and is being broadcast across six continents to over 150 countries, with more than one billion people expected to see it in total.
Beyonce said: 'I am really happy that so many amazing artists and presenters have come together to support Chime For Change on June 1.
Royal seal of approval: Prince Harry delivered a message to the audience via videolink as the concert got underway
Pins on parade: Ellie Goulding put on a leggy display as she took to the stage later on in the evening
'Our goal is to have a great time together while we unite and strengthen the voices of girls and women around the world.'
Madonna, who is helping to host the event, told the Chime for Change website: '60 percent of the children in the world not in school, are girls. 2/3 of the world's illiterate are women. Do not accept this. We need to change this and we will change this.'
Also performing are Ellie Goulding, Jessie J, Florence + The Machine, Haim, Iggy Azalea, Jennifer Lopez, John Legend, Laura Pausini, Rita Ora and Timbaland.
