Blac Chyna ‘Grabs A Bottle In New Reality Show To Fight Her mom’

Blac Chyna is keeping things real on her new show, even if that means kicking her mother's ass on camera or vice versa.

Sources tell TMZ ... BC's reality series, "The Real Blac Chyna" is 100% unscripted, meaning producers decided to simply follow her around and shoot everything as it happens. That includes some wild footage in a teaser trailer that shows Chyna and her mom, Tokyo Toni, coming to blows at home.

Toni and Chyna have a legendarily toxic relationship -- which, of course, makes for great TV and they didn't disappoint.

TMZ sources say the physical altercation you see in the trailer broke out when Toni started yelling at Chyna to get her ass into therapy.

You can tell mom knows how to push Chyna's buttons, and it wasn't until the women seriously went after each other -- Chyna grabbed a bottle -- that production staff broke it up.

Unlike other reality shows that use loose scripts and outlines to manufacture drama, thy are told Chyna's producers are shooting unfiltered and largely uncut. Whatever the cameras catch is what you'll see.
