According to a tweet from LeAnn, the fellow diner came up to her table and told her she needed to "Eat something" in front of her stepsons Mason and Jake.
LeAnn tweeted, "What is wrong with people!?? AS I'm stuffing my face…have another drink and maybe take a class in manners! Cheers!"
A source says the pair looked like they were having fun, but attempted to go unnoticed: Rimes wore a fedora and kept a low profile while dining.
