MUSTWORTHINESS After holding her own opposite Eminem in ''8 Mile,'' the giggly New Jersey native romances the tome in ''Little Black Book,'' which opens Aug. 6. Starring opposite Oscar winners Kathy Bates and Holly Hunter as a producer on a Jerry Springer-like talk show (''My Grandmother Was a Hooker!''), Murphy uncovers the secret life of her boyfriend (''Sex and the City'''s Ron Livingston) when she thumbs through his Palm Pilot.
PALM PILOT OR BLACKBERRY ''I own a BlackBerry. It's blue. So I call it a BlueBerry!''
ON HER MUST LIST [The CD] ''Carmen McRae Live at Birdland West''
NEXT The dark thriller ''Sin City,'' codirected by Robert Rodriguez and Frank Miller; singing a Queen ditty and ''Boogie Wonderland'' as a penguin in George Miller's animated ''Happy Feet'' (due in 2006); ''and I'm recording an album.''
WAIT! REALLY? CAN SHE TELL US ANYTHING ABOUT IT? ''No'' [big giggle].
