The Halo star has previously supported a number of good causes through her #BeyGOOD initiative, handing out school supplies to students across the U.S. and providing money to help a church charity mission in her native Houston, Texas.

She is now turning her attention to the residents of Flint, Michigan, who have been unable to use their water supplies since 2014 due to pollution in a local river, by providing assistance to the United Way of Genesee County organisation and the Community Foundation of Greater Flint, which are offering aid to residents.

A statement released by tour promoters Live Nation Entertainment, the company behind Beyonce's newly-announced The Formation World Tour, reads, "True to her life's work of always giving back, fans will be given the opportunity to participate in Beyonce's #BeyGOOD initiative supporting local United Way programs and the continued work surrounding the water crisis in Flint, Michigan. United Way of Genesee County has been at the forefront of distributing thousands of filtration pitchers, faucet mount filters, replacement cartridges and truckloads of water to underserved (sic) populations to address immediate needs in Flint Michigan.

"They are also partnering with the Community Foundation of Greater Flint to create a fund that will address long-term developmental, education, nutrition and health needs of the children affected by the Flint Water Crisis."

Beyonce is one of many celebrities offering aid to those affected by the water crisis - Madonna, Pearl Jam, and The Game have donated money, and Cher, Sean 'Diddy' Combs, Mark Wahlberg, and Eminem are among those who have donated bottles of water.

Beyonce surprised fans by releasing new single Formation ahead of her appearance at the Super Bowl half-time show on Sunday (07Feb16), and after her performance, she announced dates for her 2016 world tour.
