Bruno Mars is currently on the North American leg of his 24k Magic world tour.
He was in Ireland earlier this year where he played two nights in the 3Arena.
During a gig in Michigan Bruno announced that he would be donating $1 million from the show to provide aid to the victims of the Flint water crisis.
According to E! Mars said "I'm very thankful to the Michigan audience for joining me in supporting this cause."
The Community Foundation of Greater Flint is currently addressing the multitude of issues facing the city after the water crisis and resulting disaster from the effects of the population's exposure to lead.
