Miranda Lambert was involved in a heated argument on Sunday at a Nashville steakhouse. She got so angry, she dumped her salad in another woman's lap. TMZreports that Miranda was having dinner at Stoney River Steakhouse with her mother and a male friend when a man started mouthing off to Miranda's friend about millennials and their phones. Witnesses say Miranda had to be held back after the man came over to her table and started shouting at them.Since she wasn't able to get to the guy, Miranda went over to his wife and dumped her salad on her. The cops were called to the restaurant, but Miranda and her guests had already left by the time they arrived. No police report was filed.
