(CNN) - Kylie Jenner may be the youngest-ever self-made billionaire. But she did NOT talk about it at the Met Gala.
The 21-year-old makeup mogul and reality star took to Twitter to respond to comments Alex Rodriguez made about their conversation at the ball.
In an interview with Sports Illustrated published Tuesday, the former professional baseball player said he and Jenner were seated at the same table at the Met Gala in May.
"Kylie was talking about Instagram and her lipstick, and how rich she is," he told the sports magazine.
Not true, Jenner shot back on Twitter. She said they -- like nearly everyone else at the time -- were talking about the television show "Game of Thrones," which was nearing its series finale.
A-Rod later seemed to walk back the comment, saying in response to Jenner's tweet that he had been the one to talk about her makeup line.
Forbes magazine named Jenner, 21, the world's youngest self-made billionaire in March, putting her in the No. 23 spot on its 2019 list of America's Richest Self-Made Women. The magazine has estimated that Jenner's company, Kylie Cosmetics, is worth at least $900 million. She owns a 100% stake in the enterprise, Forbes has reported.
The designation, however, stirred up some drama because some argued that having a wealthy, famous family makes it hard for her to be "self-made."
