Rapper Big Boi, half of the group Outkast, was robbed by a gang of young boys in the Dominican Republic. 

The rapper made the mistake of giving some money to a boy that was begging for money on the side of the road, and things quickly got out of control.

The rapper was driving a four wheeler in the middle of the Caribbean nation's countryside, when he came across the group of boys.

As soon as the rest of the boys saw that Big Boi was giving out money, they swarmed his vehicle and wouldn't let him leave until he gave out every dollar in his pocket.

The Atlanta rapper attempted to drive away, but the boys jumped into his vehicle, and wouldn't allow him to escape.

Eventually Big Boi ran out of money, and the boys allowed him to leave.

Here's the video:

According to new reports, The Outkast rapper -- who performed with Adam Levine and co. during the Super Bowl LIII halftime show -- is continuing his generosity and is set to announce today a joint donation of $100k from himself and the NFL. We're told the money will be going to the Martin Luther King Jr. Center for Nonviolent Social Change in Big Boi's hometown of Atlanta.

Sources familiar with the deal told TMZ ... the joint donation is similar to the ones the league made with the other halftime performers in Atlanta. Maroon 5's went to Big Brothers Big Sisters of America, and Travis' went to Van Jones' Dream Corps.  

Their donations were announced before the big game, but we're told Big Boi always intended to make one too. He just took longer to announce it because he needed time to decide where the money would be put to the best use -- and The King Center won out.
