Kendall Jenner, who has famously appeared on the reality show Keeping Up With the Kardashians since the age of 11, says that she was raised right. The model, 18, came to her own defense on Twitter on Tuesday evening, Aug. 12, after word spread that she was rude to a waitress. She cited her upbringing as proof that she wouldn't do such a thing. 

This past weekend, The New York Post's Page Six reported that Jenner was recently dining at New York City restaurant Mercer Kitchen with her friend Hailey Baldwin (daughter to Stephen Baldwin), when things took a turn for the dramatic. 

The underage Jenner and Baldwin, 17, reportedly asked for alcoholic drinks, but were turned down because they are not yet 21. The pair then allegedly left the restaurant without paying for the food they had already ordered and eaten. 

Serving the girls was MTV Skins alum Blaine Morris. Jenner reportedly threw $20 bills in her face when she approached the stars about their payment. She tweeted at the time, "That horrible moment you chase a Kardashian down the street because she forgot to pay her bill to be thrown money in your face." The message has since been deleted, however.

"These rumors r absolutely ridiculous!" the daughter of Kris and Bruce Jenner tweeted on Tuesday. "I would never throw money in anyone's face or act that disrespectfully. I was raised better than that."

"Said it once and I'll say it again, don't believe everything you read!" she continued.

For her part, Morris has yet to comment on the incident since it went public.
