Star slams Kylie Jenner/Tyga chemistry in 'Stimulated' video

Tyga's new 'Stimulated' video could be getting him the much-needed attention after all.

Now, Kim Kardashian has allegedly blasted the rapper's on-screen romance with her sister Kylie Jenner, calling it "mediocre" and compared to her own cameo on 'Bound 2' with Kanye West, Kylie is just an "amateur"! Ouch!

Reports say the pregnant star is not exactly impressed with the make-out-filled video. In fact she thinks Tyga was trying too hard to re-make Kanye's 'Bound 2' video.

A source tells HollywoodLife, "Kim saw Kylie and Tyga’s ‘Stimulated’ music video and she wasn’t impressed. She thought the song was just OK and felt the chemistry between Tyga and Kylie was mediocre." Is Kim feeling a bit jealous of her now-grown-up baby sis, and wants to remind her that she is queen!

The source went on say that "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 the video."

"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!" source added.

Well, there’s no denying that 'Bound 2' is one of the most-talked about music videos to date but isn’t Tyga's new video worth the competition?
