Blac Chyna Disses 'Tacky' Kylie Jenner: Nasty 'Toothbrush In Toilet' Prank Amuses Tyga?

Rumors suggest that rapper Tyga recently gave (ex) baby mama Blac Chyna an exclusive tour of Kylie Jenner's private home - behind the 17-year-old beauty's back! Such untrustworthy behavior angered the "Keeping Up With The Kardashians" youngster enough, but the nasty prank that Chyna pulled in her bathroom proves even more upsetting!

The former hip-hop video vixen isn't very nice when it comes to respecting T-Raw's new girlfriend. Maybe she's just jealous, which leads to rather immature and bratty behavior. But Chyna took things too far while touring Jenner's house (basically uninvited):

"She thought Kylie's house was completely deplorable. It was just tacky to her," an alleged insider tells the popular gossip webloid HollywoodLife.com. "But badmouthing her place was the least of it. Blac had to use Kylie's bathroom, which is where the trouble really started. "She thought it cluttered and was smaller than a bathroom at an outdoor concert. When she washed her hands she saw Kylie's toothbrush and it was all bad from there. She took the brush and swirled it around in the toilet water before putting it back on the toothbrush holder - walking out like nothing happened. It was one of the most joyful bathroom experiences Blac's ever had in her life."

Totally gross! Will this icky prank finally throw Jenner over the edge?

Apparently, Chyna was extremely curious about the teen's luxurious mansion. The "Rack City" emcee felt massive pressure, so eventually snuck his former lover into the residence. Obviously, the bootylicious Instagram bombshell wasn't too kind:

"Blac had a field day inside the house," another snitch reveals. "She walked through every single room critiquing the place, mostly saying s-t like 'that's ugly' and 'this girl has no taste."

And Jenner wasn't too pleased once she discovered her beau's betrayal:

"Kylie was pissed, absolutely pissed that Tyga would go behind her back and pull a bullsh*t stunt like that... She told him she couldn't believe he would betray her like that and how could he disrespect their new home by bringing that trash over."

Can MstarsNews readers blame her for being so mad?
