Rapper Tyga's latest music video "Stimulated" is causing controversy since it dropped on Sunday, especially since it features "Keeping Up with the Kardashians" star Kylie Jenner as the leading lady who loves on the rapper, flaunting the rumors that they are in a relationship.

As if the body language between the two aren't enough to convey that message, the NSFW song's tactless lyrics imply the couple had a romantic past, perhaps before Jenner's 18th birthday on Aug. 10.

Tyga has not said who the song is about, but the music video is filmed at an oceanfront house where he and Jenner kiss, cuddle and flirt while he sings the lyrics, "They say she young, I should've waited / She a big girl, dog, when she stimulated."

In another scene, Tyga gives her a piggyback ride, which loses its playful romanticism thanks to the continuation of Tyga's crass lyrics, "I'm puttin' in, I'm penetratin' / I'm getting' big, I'm stimulated / I touched the b*tch, she disintegrated."

The song and video do not sit well with many critics, including Teen Vogue who reports that in it the "Ride Out" rapper is justifying -- and seemingly glorifying -- his illegal sexual encounter with an underage girl.

In the video, Tyga boasts about sleeping with a girl, who may or may not be Jenner. "But throughout the song, he's essentially peacocking, showing off to other men that he's 'scooped up' a minor," writes Teen Vogue's Casey Lewis, adding that "It's not a long shot to say that 'Stimulated' sounds a little like justification for statutory rape."

"Stimulated" has received mixed reviews from people on Twitter.

There were also tweets in support of not only the song, but the celebrity couple:

@Darling_kassie tweeted on Monday, "I'm in love with Kylie Jenner and Tyga's love #KylieJenner #Tyga ##Stimulated @KylieJenner @Tyga."

@Zee_Se7en tweeted, "#NP @Tyga Stimulated is actually really good track!!!"

Jenner was rumored to have been dating the rapper, 25, since last fall when she was 17. The pair vehemently denied a romantic relationship.
