**WARNING -- THIS VIDEO CONTAINS EXPLICIT LANGUAGE**

A video has surfaced showing rapper Gunplay getting his head slammed into a metal barricade outside the BET Awards Sunday night in Atlanta -- and it appears 50 Cent was part of the violent mob.

The clip shows 50 in the parking lot with his crew -- and out of nowhere, a massive brawl breaks out ... with rapper Gunplay on the receiving end of a ferocious attack.

Gunplay weathered the initial onslaught and managed to fight back, even though he was largely outnumbered.

It's hard to see in the shaky footage if 50 threw a punch -- or got involved at all -- but someone can be heard on camera saying, "That was 50 fighting too!" Gunplay called in to TMZ Live Monday, saying 50 Cent was involved in the action ... but was "hiding behind security."

We reached out to 50 for comment, so far no word back -- but G-Unit rapper Mike Knox (who appears in the clip) said in a radio interview this morning, "The only thing I can tell you is [Gunplay] was in the wrong place at the wrong time and he was acting a certain kinda way that he shouldn't have been actin' ... So, he got dealt with ... He got his ass kicked."

The video was first posted on WorldStarHipHop.com.

Gunplay says he absolutely DID NOT fire a gun at the BET Awards ... but claims he DID beat up a member of 50 Cent's entourage ... and says he wants to "kill" everyone in the G-Unit crew. 

Gunplay -- a rapper who's signed to Def Jam -- just called in to TMZ Live to talk about the madness at the BET Awards in Atlanta on Saturday ... where multiple fights broke out behind the scenes.

Gunplay tells us ... he "had to fight off five dudes" who he believes were members of 50 Cent's camp.

Gunplay says things got violent with 50's group because, "I never liked them and always wanted to kick his ass ... and I finally got the opportunity."

The rapper says 50 Cent WAS involved in the action ... but was "hiding behind security." Gunplay says he was trying to "break his f*ckin' neck."

Gunplay says he did manage to beat down one of the guys in 50's entourage -- "kicked one of their fat-asses ... kicked them off in the dirt." Gunplay says cops then rushed in and sprayed him with mase.

Gunplay -- who's friends with Rick Ross -- says his fight had nothing to do with Rick's altercation with Young Jeezy's crew at the BET Awards ... but explains, "We just goin' at it with everybody ... let's go kill 'em all."

Doesn't sound like he was joking ... Gunplay told us, "If you're playin' with me, you're playin' with fire ... might get gunned down, ya never know."

The BET Awards brawl between Rick Ross and Young Jeezy took an army of guards to break it up and left a trail of destruction backstage -- and TMZ got the intense footage on tape.

In the video, security can be seen stepping in between the various combatants almost immediately, separating everyone before the fight got out of hand.

A shirtless Rick Ross can be seen yelling before being escorted away from the scene. Whoever Ross was yelling at tried to follow after him, but security stepped in before he could get there. 

There was one casualty however -- a random mirror.

According to Atlanta PD, no arrests were made.

50 Cent wasn't too phased after attending the BET Hip Hop awards last night -- despite the 911 calls, alleged back-stage brawls and reported gun shots -- telling TMZ it was just a regular awards show.

We caught up with 50 arriving in NYC directly after attending the awards show in Atlanta. As TMZ previously reported, Atlanta Police were called after a crazy fight allegedly broke out between Rick Ross and Young Jeezy (and a few people reported hearing gunshots). We're also told 50 got into it with a rapper named Gunplay. 

But when we ask 50 to explain the craziness surrounding the night's events, he said nothing happened except ... "They gave out awards."

Clearly.

A fight broke out backstage at the BET Hip Hop Awards tonight between Rick Ross and Young Jeezy that resulted in shots being fired .. sources at the awards tell TMZ. 

According to our sources, Ross and Jeezy exchanged words backstage and started pushing and shoving each other. We're told BET security and bodyguards for each of the rappers eventually separated the two.

Our sources on the scene say that after the fight had been broken up, a member of Rick Ross' entourage pulled out a gun while in the parking lot and shots were fired.

We're told Jeezy and Ross are still at the awards, which are being taped tonight in Atlanta and air next month.



A spokesperson for the Atlanta Police Department tells TMZ, "Shortly after 7:15 pm Saturday, a fight broke out in the parking lot at the Atlanta Civic Center (where the BET Awards were being taped) between two groups. Atlanta Police Department officers on scene responded to break up the fight and used OC spray in the process. Individuals fled the scene. There were no arrests or reports of serious injuries. Reports of shots fired appear to be untrue." Our sources maintain shots were fired.

We're also told that 50 Cent got into it with a rapper named Gunplay, a protégé of Rick Ross. 

Can't we all just get along?

A rep for BET tells TMZ, "BET Networks works very hard to bring the best in entertainment to the city of Atlanta. For the past 7 years BET has celebrated the true art form of Hip Hop. Due to some misjudgment of select attendees, it is unfortunate that certain incidents took place. BET Networks does not condone any type of violence. Local authorities are working to resolve the situation as quickly as possible."

1:00 PM PT -- Mindless Behavior just apologized for the diss, tweeting, "We meant no disrespect to our girl Lauryn Hill last night, it was a bad joke. We're big fans and hope you're not mad!"


Beyonce wasn't laughing when a boy band DISSED Lauryn Hill at last night's BET Awards ... in fact, Bey was so upset, she changed her acceptance speech (on the fly) to HONOR the former Fugee.

So let's start with The Diss -- Comedian Mike Epps and the group Mindless Behavior were co-presenting the award for Best R&B Artist when Mike jokingly tried to sing.

One of the members of the group quipped, "You sing BAD ... like Lauryn Hill's tax accountant bad."

The diss drew gasps from the crowd ... and pissed off Beyonce, who ultimately WON the award that was being presented.  

But TMZ has learned ... B was so upset, she scrapped the speech she had prepared and defended Lauryn's honor instead ... saying, "I want to thank all the talented R&B women that came before me like Lauryn Hill and Mary J. Blige."

When B walked off stage, there was a woman waiting for her -- possibly a BET handler -- and B began to vent about the insult, saying the Lauryn Hill diss was "disrespectful" and "not cool."

The woman complimented Beyonce for adding Lauryn Hill's name to her acceptance speech ... to which Beyonce replied, "I just felt [the diss] was wrong."

We called Beyonce's rep for comment -- so far, no word back.

You might think Chris Brown would be persona non grata at the official BET Awards after party tonight, but TMZ has learned the nightclub combatant was indeed invited and RSVP'd yes.

According to our sources, CB will be in attendance at the star-studded soiree going down at Playhouse in Los Angeles ... where Usher, Common, and Kevin Hart are among the anticipated guests.

We're told Brown's people told party organizers the singer will be showing up and that the invite came AFTER the events that went down at W.i.P. in NYC. In fact, the party tonight is being thrown by people connected to W.i.P.

Our sources say Drake and Meek Mill were not invited to the party to avoid any potential incident. Drake is not expected to be at the BET Awards, while Meek Mill is scheduled to perform.

Heavy D was planning a huge comeback just before his death -- and those plans included a new music video.

Carl Thomas, who sang on Heavy D's latest album, tells TMZ, he was in touch with Heavy two weeks ago ... and Heavy told him he was weeks away from shooting a music video for their song, "Still Missing You." Thomas said Heavy had a director in place and had picked a location for the shoot.

Sources close to Heavy D tell us it was all part of the singer's comeback plan. We're told he released his new album on September 27 because it coincided with the BET Music Awards ... and he was hoping the performance would put him back on the map.

As we first reported, Heavy D passed away on Tuesday after collapsing outside his Beverly Hills home. He was 44.

Justin Bieber's entourage and security at the BET Awards got into a heated showdown -- which ended with JB declaring the doorman was "a douche bag" ... and the whole incident went down on camera. 


TMZ obtained the video, which shows Bieber -- who was a presenter at the award show -- and his squad being stopped at the door last weekend. It appears one of Justin's bodyguards did NOT have a ticket ... and while both sides argued, Biebs eventually interrupted by saying, "I need to bring my security! This guy's a douche bag."

Everyone on Team Bieb ended up getting into the show -- and a BET rep downplayed the incident ... saying, "It is our standard policy to make sure everyone has their tickets or credential upon arrival. Justin had the proper credentials."
 
As for Justin -- his rep says the Biebs was just standing up for his bodyguards ... the guys who always have his back.

Wanna see a REALLY, REALLY awkward moment at the BET Awards??? Look no further ... 


Some "lucky" BET viewers were chosen to present the viewer's choice award at the show last night ... but there was a HUGE mistake ... because someone put the wrong name on the teleprompter. 

So the lucky fan read the winner as "Chris Brown" ... but quickly recanted and said, "I'm sorry, the winner is Rihanna."  But that wasn't the case either ... 

Despite the fact that Rihanna's name appeared on the video screen as the winner ... one of the presenters chimed in for a THIRD time and announced Drake as the winner!!! Drake then appeared on stage to collect his trophy. 

Drake gave a short speech and described the whole thing as awkward. Understatement. 

After the awards, a BET rep announced that Brown was the correct winner -- and chalked the whole thing up to a "human error" on the part of BET producers.

We took your questions on everything -- including Bruce Beresford-Redman's cell phone extradition defense, Lindsay Lohan being sued by a clothing boutique, and Vienna Girardi's wild spring break photos.
