Chris Brown My Lambo's Got the Blues ... Even Though I Rep Bloods

Chris Brown loves throwing up Bloods gang signs, but you can't tell by looking at his ride -- he just dropped $10,000 to turn his Lambo ... BLUE!

Chris hit up JC Customz in Bellflower, CA shortly after being released from jail to get a fresh new look for his 2013 Lamborghini Aventador. It's not quite Crips blue ... in fact we're told it's a custom shade called Sky Blue.

The car -- which was previously designed to look like a Nike Air Foamposite Camo sneaker -- had to be totally stripped down during the month-long process, repainted, and then put back together ... according to the shop.

It's no secret Chris likes to design his exotic cars with cool looks ... check out his other creations.

Blac Chyna Cops Impounded My $300k Ride

Tyga's baby mama has some 'splaining to do ... because Sunday in Malibu she got their Rolls-Royce Phantom impounded -- for a really dumb reason.

Law enforcement sources tell us Blac Chyna was pulled over after cops got complaints a matte black Rollie was being driven erratically ... and since there aren't too many of those $300k whips toolin' around, they quickly found Chyna and pulled her over.

That's when the real trouble began ... during the stop, cops ran BC's plates -- she was driving without a license, so they impounded the vehicle -- and will only release it to a licensed driver.

Better hit up the DMV, stat.

'Fast & Furious 7' Racing Scene SCRAPPED We Can't Tolerate Another Death

A critical scene for the upcoming "Fast & Furious 7" came to a screeching halt Thursday ... after studio suits pulled the plug because it was just too dangerous ... too risky.

Sources connected with the production tell TMZ ... the shoot was being prepped at the Willow Springs International Raceway near Palmdale -- 45 minutes from where Paul Walker tragically died.

Members of the crew tell TMZ ... producers brought in drivers who are "authentic street racers" for the scene, where a souped-up yellow Chevelle races another car and dramatically pops a wheelie, as bystanders stand right by the track and cheer. A similar scene appeared in the first F&F.

The scene was being prepped for several days. Vin Diesel and other stars were there. But just before filming, we're told the suits from Universal abruptly cancelled the shoot, saying it was too dangerous.

Someone who was at the track tells TMZ ... a person from the production told some staffers they couldn't get the proper insurance to shoot the race.

But the word circulating among the staff is that they are extremely cautious because of what happened to the star of their movie. They believe a second crash -- even though Paul's was not film-related -- could jeopardize the entire franchise.

Justin Bieber was a full-on good Samaritan Sunday ... rushing to the aid of 3 of Floyd Mayweather's kids who were involved in a bad car crash.

Here's what we know. Floyd was on the red carpet Sunday afternoon for the BET Awards when he got word his kids were in a bad crash in L.A. Floyd happened to be on the phone with Bieber at the time and told the singer how bummed he was that he was on the red carpet and not there for his kids.
