'Star Magazine' claims that Jessica Simpson's kidney infection last month was the result of several months of hard partying and heavy drinking with Tony Romo.

Jessica was rushed to the 'Cedars-Sinai Medical Center' in L.A. on March 28 and remained there for four days. Her spokespeople said that she was being treated for a kidney infection, but an insider revealed that Jessica's health problems were "a kidney infection, a bladder infection, and a urinary tract infection which were brought on by drinking an obscene amount of alcohol. She used to keep her drinks to a minimum but Tony and his buddies really party hard, and I think they expect Jessica to keep up with them".
