LeAnn Blows Up On Twitter About Weight Loss

It had to explode at some point: LeAnn Rimes Cibrian furiously took to Twitter to berate a fellow diner who caught the singer and her husband eating at a Chicago restaurant on Friday night. Addressing the person who apparently suggested that the star was too skinny, she wrote:

How dare someone come to me at a table w/ the boys & tell me I need to eat something. What is wrong with people!? AS I'm stuffing my face....have another drink and maybe take a class in manners! Cheers!

Photos of the 28-year-old have been publicized since April, when a drastically slimmed-down Rimes appeared at the NCAA basketball championship game in Houston to sing the National Anthem, then, months later, shared bikini photos of herself on the beach.

Perhaps, in an effort to negate claims of an eating disorder, Rimes followed up with this tweet on Saturday: "Pizza and chinese food for us for the night."
