The head of the Nation of Islam religious group held a rally at the Tindley Temple United Methodist Church in the Men In Black star's native Philadephia, Pennsylvania recently and revealed the couple had made the sizeable contribution in support of the organisation's efforts to raise $1.8 million (GBP1.1 million) for the cause.

During the rally, Farrakhan also called on other celebrities to donate.

The Justice…Or Else! march will take place on 10 October (15) at the National Mall in Washington, D.C. to commemorate the 20th anniversary of Farrakhan's Million Man March.

Earlier this summer (15), rapper The Game met with the spiritual leader to discuss plans for the march, which is expected to draw thousands to the capital following a series alleged police brutality incidents involving black youths across the U.S.
