The teenage model was pictured out and about in Los Angeles with Scott, who is dating her elder sister Kourtney Kardashian.
Kendall and Scott were snapped heading into Barney's New York department store for a spot of retail therapy on Monday, 20 April, the day after Kendall returned home from Coachella.
The 19-year-old has been The It Girl of this year's Indio, California music festival, attending both weekends and partying up a storm with a string of celeb pals including Justin Bieber and younger sister Kylie Jenner.
Yesterday, she switched her rock chick festival clothing for a cute green jumpsuit as she joined her big sister's boyfriend in LA.
Earlier this year, Kendall and Scott laughed off claims of a shock secret affair that emerged in a US tabloid, poking fun at the rumours via social media to make sure everybody knew how ridiculous they were.
Even Kendall's big sister Khloe got in on the act!
Khloe took to Twitter to lament: "I'm really pissed about this whole Kendall Jenner and Scott Disick thing. Scott, I thought it was you and I that was having the affair!"
Scott also got in on the joke, replying: "Don't worry Khloe, you will always be my number one."
Um, what, said Kendall! She joined in the fun, sending a message to Scott saying: "Excuse me?!"
