Kendrick Lamar Beats Fan, Rapper Leaves Groupie 'Bloody' After Violent Las Vegas Hotel Room Fight, Charges Soon? [VIDEO/RUMORS]

If these rumors surrounding a Memorial Day "beat-down" involving rapper Kendrick Lamar prove true, the "Poetic Justice" emcee could find himself in some BIG trouble with the law.

According to an alleged MediaTakeOut.com "snitch" who works security at Las Vegas' infamous Hard Rock Hotel, police recently investigated Lamar regarding a violent fight that took place in a luxury room back in May. Apparently, the 27-year-old singer "brutally beat" an unidentified female fan later called security for help. When hotel guards arrived, they found the victim a "bloody mess."

Check out this recent Youtube edition of "Friday Night Live From #TheLoveRanchNorth" (originally posted via MTO). The rumored "witness" insists that the female fan plans on pressing charges against Lamar soon, although no one actually saw the attack happen:

The security rep reveals in the clip (around the 57-minute mark):

On Memorial Day Weekend... so I get dispatched up to one of the rooms to help some girl get down to the casino. She ends up being all bloody and things, so I had to call my supervisor, then I had to call my other supervisor, then I had to call my boss. And I was like, "We have a situation," because half of her face was like blown out.

Come to find out that she was with a certain rapper, who had assaulted her... and his first name is [Kendrick]. [Audience asks if she means Kendrick Lamar]. Yeah... He beat up some chick, [and] there was like blood everywhere.

There were cops there, and we didn't find out it was Kendrick until later... She ended up pressing charges, I think.

Crazy stuff - stay tuned as more details develop. Lamar has yet to respond.
