The reality teen - who split from her rapper beau earlier this month - was responding to a fan who had read the story on U.S site Baller Alert, and instantly dismissed the rumours as a load of rubbish.
On the social media site, the user had wrote: "Just read on @balleralert that @Tyga finessed @KylierJenner out of 2 Mil hahahaa #FINESSED."
Clearly feeling annoyed about the claims, the Keeping Up With The Kardashians star replied with: "Lies lies lies."
Kylie, 18, is estimated to be worth millions thanks to her super popular Lip Kits line, as well as numerous other projects. At 17-years-old, she purchased her first ever house for $2.7million and just a few weeks ago she upgraded to a $6 million mansion. Yep, really!
But with Tyga's own successful music career, it's hard to imagine why the 26-year-old would need to borrow dosh from Kylie.
Kylie and Tyga confirmed their relationship in 2015, shortly after Kylie turned 18. The pair parted ways recently, but Tyga admitted he still loved the star.
However, it seems that both of them have now moved on. Tyga is now dating British lingerie model Demi Rose Mawby, whereas Kylie has been linked to Canadian rapper PartyNextDoor.
