Rapper The Game arrives at the BET Awards '11 held at the Shrine Auditorium on June 26, 2011 in Los Angeles

*TMZ is reporting that a producer was held up at gunpoint while working on a music video for The Game and Chris Brown, losing more than $12,000 in cash and jewelry

The armed robbery took place Tuesday in South Los Angeles, according to law enforcement sources. The producer was reportedly sitting in his car with another person when two black male suspects walked up, pulled out a gun and demanded the items. They reportedly escaped in a gray Nissan Altima.

Sources on the music video shoot say the producer, named Mars, had walked about a block from the set when his jewelry and his wallet — stuffed with a couple thousand bucks — got jacked.

A rep for Game said everyone on the set is supposed to have security while walking around the neighborhood. A TMZ camera guy was on the block when Game got word of the robbery and started chewing out his security team. Watch here .
