Granted, Jada Pinkett-Smith may be under investigation (for failing to discipline her own children), but she apparently has no problem laying down the law with other people's kids.
Star magazine reports that Jada recently banned Kendall Jenner from her home for copping an attitude with the Smith family's longtime housekeeper.
"Jada took an instant dislike to Kendall; she's got a rude mouth on her," a source tells the tabloid. "The way she spoke to Jada's housekeeper was atrocious and arrogant."
Hilariously, the final straw reportedly involved Kendall behaving rudely while being served iced tea:
"[Kendall] rolled her eyes and huffed like the maid was stupid when she asked if Kendall wanted sweetener for her iced tea!"
Jada reportedly witnessed the breach of etiquette, booted Kendall from her house, and instructed the Instagram Queen to never return.
"Jada's not having it - she was raised by a single mom and doesn't let that kind of snobbery go on under her roof," says the insider.
That makes two bizarre controversies in as many days for Kendall:
Yesterday the teenaged Jenner sisters partied with shirtless grown men in the Hamptons, leading many to wonder if there is any parental involvement in their lives at all.
