Kendall Jenner may not be as sweet and innocent as she appears to be on her reality show. News broke on Monday that the 18-year-old reportedly refused to pay her $60 tab at the pricey Mercer Kitchen in New York last week, though with her numerous modeling campaigns, she certainly has the cash.

The reality star’s server was Blaine Morris, who, as it happens, starred on MTV’s short-lived teen drama “Skins” as Betty Nardone. Morris ran outside the restaurant to chase Jenner after "she left and didn’t pay for all the food . . . about $60 worth,” a source told the New York Post's Page Six. She also left without leaving a tip. The young starlet was reportedly unhappy because “the staff wouldn’t serve her [booze] because she’s underage."

When Morris ran after Jenner, who was accompanied by actor Stephen Baldwin’s daughter Hailey, the two young celebs laughed. Jenner then “took a couple of $20 bills out of her wallet, threw them at the server and walked away, not even counting if it was enough or if it included a tip.” Morris later tweeted, “That horrible moment you chase a Kardashian down the street because she forgot to pay her bill, to be thrown money in your face.”

Jenner’s rep did not comment, but Baldwin’s rep said, “They thought everything was paid for. Kendall was polite and asked, ‘Does this cover it?’ They didn’t run.”

Meanwhile, Jenner seems to be following in older sister Kim Kardashian’s footsteps and pairing up with athletes. The statuesque beauty is reportedly dating NBA player Chandler Parsons (Kim married NBA player Kris Humphries and infamously split with him after 72 days). The Dallas Mavericks small forward recently signed a three-year, $46 million deal. Jenner and Parsons hung out at STK LA along with Jenner’s sister Kylie and two other friends. “Kendall and Chandler were flirting throughout the meal,” a witness told Page Six. “They laughed and chatted all night.”
