Tyga and Kylie Jenner have given up trying to conceal their romantic relationship. Rumors have been circulating about the pair since September 2014, shortly after the “Hookah” rapper called off his engagement to Blac Chyna. Both Tyga and Jenner, 18, maintained that they were just friends, though few believed them. Now, it seems clear they’re an item and they don’t care who knows it.

As was reported by Entertainment Tonight, Tyga, 25, released the video for his latest single, “$timulated,” on Monday. The video, which takes place in an over-the-top mansion in Malibu, California, shows Tyga hard at work on a song when Jenner arrives in a bright green Bentley coupe. Shortly after walking through the doors of the massive mansion the “Keeping Up With the Kardashians” star is greeted with a hug and a passionate kiss -- one of many that take place during the video. They can later be seen sharing a romantic moment and taking in the picturesque views on the balcony of the multi-million dollar home.

The video quickly became a topic of discussion among Twitter users. Many took to the social media site to express their feeling that, although Jenner is now a legally consenting adult -- she turned 18 on Aug. 10 -- her relationship with Tyga is inappropriate. Some simply focused on his music, slamming both his talent and ability as an artist.

Tyga and Jenner made their first public appearance as a couple on Sunday. The pair were seated together, alongside Jenner's entire famous family, in the 2015 MTV Video Music Awards audience. During the show the cameras panned in on the rumored couple, who posed for the cameras by leaning into one another and making faces at the photographers.

It was widely believed that Jenner was the woman Tyga is rapping about in "$timulated," though neither spoke on those claims. "$tiumlated" features NSFW lyrics about an unnamed female subject. In the single, off his latest album “The Gold Album” released on June 23, Tyga says, “they say she young, I shoulda waited / she a big girl, dog, when she stimulated.”

Tyga's music video marks the first time he and Jenner have in any way acknowledged that there is something romantic between them. Their friends and family, however, have not shied away from the subject when asked. During an interview with Complex for their August 2015 issue, Jenner's older sister Khloé Kardashian admitted that they were dating. She rationalized Jenner's decision to date an older man by saying she was doing the same thing at her age. She added that Jenner is "not a normal" teenager as she spends much of her time in business meetings with important people in the industry.

Kanye West, who is married to Jenner's older sister Kim Kardashian, also commented on their relationship. In an interview with Power 105.1's "The Breakfast Club," West, 38, told the radio show's hosts he thought it was wise of Tyga to snatch up Jenner while he could. The telling conversation took place just days after Tyga had appeared on the same radio show and denied having a relationship with Jenner.

"I think he got in early. I think he was smart," he said.

Neither Jenner nor Tyga has responded to the criticism of the "$timulated” music video or their relationship. Check out the controversial music video below:
