Sources are saying that Jessica Simpson's "kidney infection" from earlier this month was actually "alcohol poisoning". • CBS head Les Moonves, Katie Couric, and CBS News president Sean McManus addressed the CBS newsroom to quash rumors that Katie was leaving before the end of her contract. TMZ claims to have sources who say Katie's reps are already in talks with CNN so that she can leave her CBS gig. Like Ashlee Simpson says, only "time will tell." [Dlisted, TMZ, Us]
