Tyga vs. Blac Chyna Beef, Baby King Cairo Custody Battle After Amber Rose Twerk-Off [WATCH]: Kylie Jenner's Boyfriend Blasts 'Unfit' Party Mom?

Infamous Hollywood socialite Blac Chyna enjoys partying - a lot. And according to ex-boyfriend (and baby daddy) Tyga, that's not proper behavior for a mom.

So, the "Bubble Butt" rapper wants full custody of the former couple's young son, King Cairo.

Meanwhile, the 25-year-old "Rack City" hypeman is currently dating "Keeping Up With The Kardashians" youngster Kylie Jenner, but that's a totally different story...

According to the popular gossip webloid TMZ, Tyga thinks Chyna needs to calm down... or else she might lose the other important guy in her life.

Apparently, the Compton native plans on filing official documents for primary custody of two-year-old King. As TMZ points-out, Tyga believes caring for their young child is not Chyna's top priority anymore. The former stripper would rather indulge in her own selfish "spectacles" involving hardcore partying and boozing.

Like this...

Not to mention, the curvaceous beauty just fell victim to the infamous "nip-slip" wardrobe malfunction while flaunting a rather racy ensemble on the streets of LA...

blacchyna: "I wanna thank all the people that came out last night to support Lashed."

Inappropriate?

The viral twerk videos really angered Tyga, and that's why he's now ready to go to court. He doesn't want his baby "raised by nannies," and he's willing to take King away from his mama if that's what is best.

The feuding ex-lovers do not have a concrete custody order yet, but so far young Kink spends more time with his mom. And Tyga's ready to change that for good.

Chyna has yet to respond... do MstarsNews readers think she's too busy shaking her booty for the cameras? Stay tuned... will a judge side with the "Faded" superstar?

Some fans think that Tyga recently cut-down on his OWN partying ways since Jenner's only 17-years-old, so she can't hit the nightclub scene yet. So is that fair to judge?
