Jessie J and Tinie Tempah performed outside the iconic Tate Modern gallery in central London last night as part of the ONE campaign.
The 'Domino' singer and 'Pass Out' rapper Tinie both tweeted their support for the cause, ahead of this month's G8 summit, and took to Twitter to share their views about the political campaign.
"About to go live on stage @Tate for the @ONEcampaignUK #agit8 check out the campaign," Jessie J tweeted Thursday (13th June) before the event. "Still so much work to do but changes are being made!!"
Jessie performed by wrapping up in a dark tan leather jacket and leather-look leggings, and was personally thanked by the ONE campaign after the show.
"@JessieJ Thanks for an incredible performance and getting out message out so perfectly," they posted to the 'LaserLight' singer. "Amazing night for everyone at ONE."
