Nicole Richie's rep has come up with another excuse to explain her client's ongoing health issues. After reports earlier today that Richie had collapsed again on the set of The Simple Life, her rep says, "In her ongoing effort to focus on her well-being, Nicole has recently been diagnosed with hypoglycemia... [She] is taking steps to manage it." (Hypoglycemia is essentially low blood sugar.) A source on the set of the show told People mag, "Four or five times she's felt really faint and almost passed out. She has to go into her trailer for a good part of the day."source
