Jessie J played live outside London's Tate Modern Gallery on Thursday (June 13) to raise awareness of anti-poverty charity ONE.

The singer was on hand to show her support for the project - which was co-founded by U2's Bono - as well as the likes of Tinie Tempah and Jake Bugg.

Before her slot, Jessie J tweeted in reference to global poverty: "Still so much work to do but changes are being made!!"

Sir Tom Jones, Paolo Nutini and Alison Moyet also took to the stage at the free pop-up concert.

As previously reported, One Direction recently issued a video call-out asking for fans to show their support to ONE and their anti-poverty campaign.

Ed Sheeran also recorded a Bob Dylan cover to show his dedication to encouraging change.
