Puma posted their own ad pic of the 18-year-old model in a sports bra top with gray sweats and black shoes, writing, "The PUMA Suede started its story in 1968. Worn by athletes, b-boys, and hip hop stars of the day. Today, the story continues on the feet of another icon: PUMA Suede, meet @KylieJenner."
That pay phone probably doesn't work, but Kylie's outfit in the spot definitely does!

Meanwhile, although their may have been some initial tension with brother-in-law Kanye West over Kylie signing with Puma, she still showed up at the rapper's "Famous" concert at the Forum in Los Angeles, along with none other than her former ex, Tyga.
The pair has been spending a lot of time together lately, after splitting up in May, and even kissed at Khloe Kardashian's birthday party at Dave & Buster's on Monday night.
