You go, girl!

Kylie Jenner clapped back at Jennifer Lopez's fiance Alex Rodriguez after he claimed, in a Sports Illustrated interview that the young billionaire talked about her finances at the Met Gala.

The Lip Kit mogul took to Twitter to contradict the claim, saying that everyone at the table -- including Donatalla Versace, sis Kendall Jenner and others, talked about Game of Thrones. That's some heady stuff, folks!

A-Rod had claimed Jenner talked about "how rich she is," after Forbes named her the youngest-ever self-made billionaire. But Kylie says NOT TRUE! Who do YOU believe?
