Meanwhile, it looks as though Kendall Jenner is slowly becoming the Jenner/Kardashian family's bad girl. The reality television star reportedly "threw money" at a waitress' face while dining at the Mercer Kitchen in New York City last Monday.

According to Page Six, the young Jenner was reportedly unhappy with her service because the waitress refused to serve her alcohol before she decided to dine and dash. Jenner was dining with Stephen Baldwin's daughter Hailey during the incident.

A source said, "Kendall got up and left and didn't pay for all the food... about $60 worth, and without a tip."
