Polite dinner table conversation is supposed to stay away from the subjects of religion, politics and money, etiquette experts agree .

It appears nobody told Kylie Jenner , who couldnt stop herself from talking about her riches at this years Met Gala in May (after all, she was crowned the youngest self-made billionaire ever by Forbes in March).

Alex Rodriguez spilled the details of his conversation with Jenner at the Met Gala in an article published Tuesday in Sports Illustrated. Jenner later denied the conversation topics.

We had a great table, Rodriguez said of his and fiance Jennifer Lopezs dinner mates at the gala. The black guy from The Wire Idris Elba, yeah, and his new wife.

Some famous singer next to me, I dont know what her name is, he continued. Versace Donatella. We had Kylie and Kendall. And we had an Asian gentleman from [Crazy] Rich Asians, the lead. Kylie was talking about Instagram and her lipstick, and how rich she is.
