CRAZY NEWS!!! On Saturday night, rapper Young Berg was BRUTALLY ASSAULTED And Robbed!!!

Here's what popped off. On Saturday night, Young Berg was having a small get together at his home in the Hollywood Hills. That's when, a group of 4 masked GOONS pushed in the house with GUNS OUT!!! The goons were described by a snitch as TWO MEN and TWO WOMEN!!!

And get this. Word is that the masked men were holding the rest of the people in the home hostage, while the WOMEN were the ones being violent - even going so far as to PISTOL WHIP Young Berg.

The goons and goonettes got away with Young Berg's chain and all his money. They also got into the pockets of every other person at the get together.

It's not clear whether police have ANY SUSPECTS in the matter.
