Model Padma Lakshmi showed her tart side while dining at a newly remodelled Fiamma in SoHo on the night of December 7.
The "Top Chef" host and judge Padma Lakshmi was escorted by a male friend when she visited the eatery.
When the chef there realised that the host was Salman Rushdie's estranged wife, he created a few special additions to her meal as a treat.
However, an eyewitness revealed that the 37-year-old screamed at the waiter for bringing the varied dishes.
"She was very rude to the waiter, and when he brought out the surprise dishes, she sent them all back to the kitchen saying she didn't want them," New York Daily quoted the eyewitness, as saying.
"The chef had one more planned, and when it came out, she literally screamed at the waiter, 'Take it away! Don't you know I'm on a diet?'" the eyewitness added.
