Kylie Jenner Disses Blac Chyna [Again]: Tyga's Girlfriend Warns Baby Mama 'Respect' Dating Boundaries, Denies Love Song Collaboration

Kylie Jenner and Blac Chyna do NOT get along - especially after the 17-year-old fashionista started dating Chyna's ex-beau, Tyga.

But according to the "Keeping Up With The Kardashians" beauty, the bootylicious hip-hop video vixen needs to "back off" and finally mind her own business.

Oh, here we go again...

An alleged source for the popular gossip webloid HollywoodLife.com reveals that Jenner's tired of Chyna's jealous antics. She needs to grow-up and accept the fact that her baby daddy's officially moved-on (with a younger chick). Bascially, she doesn't want an all-out catfight! The source explains:

"She's not trying to develop anything with Tyga's exes. She has nothing against [Chyna] either. All Kylie wants her to do is to respect the boundaries between her and Tyga and everything will run smoothly."

The aspiring model is trying to be mature about the whole awkward situation:

"She knows that Blac Chyna and Tyga will have to cross paths often because of their son," the snitch continues. "But other than that, Tyga's made Kylie very aware that his heart belongs to her."

But is she still "shading" Chyna via Instagram on the down-low?

And despite all of the drama, are Jenner and the "Rack City" emcee really "in it" for the longrun?

Meanwhile, another insider claims that Jenner is not intimidated by Chyna in any way, despite their recent Instagram beef:

"Kylie is not at all threatened or intimidated by Blac Chyna. Kylie doesn't know why Blac Chyna would post a picture of the watch Tyga gave her years ago, but whatever her reasons are, Kylie wants her to know exactly what time it is and that she needs to fall back when it comes to Tyga."

Meanwhile, Kim Kardashian's younger sis recently debunked rumors that she "secretly" recorded a love song with Tyga and Iggy Azalea. She tweeted:

@KylieJenner: @kingmarack *sigh* fake."

@KylieJenner: "Not releasing a song."

She'll express her affections in another way.
