That B-list flu strain rocking Hollywood has claimed another victim: Jessica Simpson. Ashlee's sis was briefly hospitalized in Chicago Monday for a stomach virus while shooting a segment for The Oprah Winfrey Show. She has since returned to Los Angeles and is "feeling better," her rep said in a statement. The Oscar-themed Oprah segment — "Red Carpet Makeovers with Jessica Simpson" — airs Friday. Just close your eyes when Jess starts to clutch her stomach.
