Jessica Simpson was at Cedar Sinai over the weekend and was released just yesterday.
She was admitted Friday after she was suffering from a fever, which turned out to be because of a kidney infection. She needed to be under medical supervision.
Jessica was released yesterday and is at home resting and recuperating.
Jessica's rep said in a statement that she's home and feeling much better now.
Her boyfriend Tony Romo couldn't be by her side ... because he had prior obligations down in Dallas.

We hope you're feeling a lot better Jess! Get well soon!
