Kendall Jenner may be 18, but a source says she displayed diva behavior at Mercer Kitchen last Monday.
Jenner was dining with Stephen Baldwin’s daughter, Hailey, and was unhappy when “the staff wouldn’t serve her [booze] because she’s underage,” our spy said.
“Kendall got up and left and didn’t pay for all the food . . . about $60 worth, and without a tip.”
Her server, Blaine Morris (Betty Nardone on MTV’s “Skins”) ran outside to ask the celebuspawn to pay her bill.
“Kendall and Hailey started laughing,” our witness said.
“Kendall 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 then 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.”
Kendall’s rep didn’t comment, but a Baldwin rep said, “They thought everything was paid for. Kendall was polite and asked ‘Does this cover it?’ They didn’t run.”
