Kylie Jenner Shades 'Fake' Blac Chyna, Stop Mooching! Tyga Threatens 'Cut Off' Warning

Kylie Jenner just celebrated her 18th birthday on Monday (August 10). Rapper boyfriend Tyga showered the "Keeping Up With The Kardashians" beauty with lavish gifts, but (ex) baby mama Blac Chyna still managed to bash Jenner's celebratory weekend. And frankly, Jenner wants the former hip-hop vixen to finally back off and focus on her own lame life!

Apparently, the brunette bombshell believes that 26-year-old Chyna is the ultmate leach. An alleged insider for the popular gossip webloid HollywoodLife.com explains:

"Maybe if Blac focused on getting a real career and stop mooching off Tyga for support, she'd be a happier woman and not so evil... But Kylie gets it though. Nobody wants to be with an aging stripper with more miles on her than a used 1990 Honda Accord!"

Ouch - that's pretty harsh! Chyna's cyber fame continues growing, but do MstarsNews readers agree that she'd be nowhere without the influence of her former "Rack City" beau?

Jenner simply wants the curvaceous Instagram model to move-on and stop trying to sabotage her blossoming relationship with 25-year-old T-Raww:

"Kylie would really love it Blac would mind her own business and take her own advice and grow up! Her continued assaults on Kylie makes her look old, tired and desperate," the snitch continues. "And in Kylie's eyes, Tyga's got more than enough money to take care of himself, King, and even Kylie herself if she wanted him to."

And the "Faded" emcee agrees:

"Kylie's 18 now and Tyga's has had enough of the games that Blac's playing," another source reveals. "Kylie means more to him than ever. She's literally his rib, and their relationship is about to get turned up two notches. He's not going to tolerate Blac trash talking his girl. That ain't cool. He's warning Blac to shut her trap ASAP! He's already taken her G-Wagon back. He can go further. He can pull the rug from underneath Blac, as well as that weave from her hair. She would want to quit while she's ahead before he revokes her seat on his gravy train." 

Wonder how Chyna might respond next?
