Kim Kardashian vs. Kylie Jenner Beef: Tyga's Mediocre 'Stimulated' Video Bores Jealous Sis

Things get EXTREMELY hot-and-steamy in rapper Tyga's new music video for the hit single, "Stimulated." Bascially, the 25-year-old YMCMB superstar makes-out with 18-year-old girlfriend Kylie Jenner the entire time. But apparently, Kim Kardashian isn't very impressed...

The (overly) sexual and sensual clip continues going viral online [WARNING, EXPLICIT CONTENT]:

So, what bothers Kanye West's pregnant wife so much? Perhaps the young couple's trying a bit too hard!

"Kim saw Kylie and Tyga's 'Stimulated' music video and she wasn't impressed," an alleged insider tells the popular gossip webloid HollywoodLife.com. "She thought the song was just okay and felt the chemistry between Tyga and Kylie was mediocre."

Ouch - maybe the "KUWTK" beauty's just jealous now that Kris' youngest offspring continues stealing the Hollywood limelight? Because the aspiring socialite still has much to learn from the selfie master...

The snitch continues:

"Kylie's attempting to steal Kim's swag and she's failing... Kim told her that 'Bound 2' was 'epic and fabulous in all proportion' and said 'the chemistry and sex appeal that my husband and I exuded can't be duplicated.' She reminded Kylie of how big 'Bound 2' was. It was the most talked about music video for months and celebrities were imitating she and Kanye's video."

But do MstarsNews fans agree that Jenner might finally be overshadowing her more famous sis? Kardasian allegedly issued this warning:

"She went further with Kylie, explaining to her baby sister that she's the original video vixen of the family and the reigning queen of television and social media too!"

Jenner might take that as the ultimate challenge! Will T-Raww now release another racy clip featuring his stunning sweetheart just to prove a point, or will KimYe still always reign supreme?
