Seriously, exactly where did Chelsea Handler come from? One day she was a virtual unknown, then suddenly there she was, all blond and tall and likable, turning the tired late-night talk-show circuit on its ear with her E! sarcasm-fest, Chelsea Lately. Its like she never even paid her dues on Oxygens Girls Behaving Badly, as a Tonight Show correspondent, or all over Comedy Central and HBO. Or that she proved her biting wit was capable of transcending both television and standup stages with not merely one but two New York Times best-sellers (involving alcohol and sleeping around, natch). And its certainly not like her In the Motherhood Internet series with Leah Remini and Jenny McCarthy was recently given a huge vote of confidence by moving into midseason development at ABC.
