A gorgeous woman
Carrerre is a decent actress (never heard her sing, but several reports indicate that she's pretty good at that, too).
But she is gorgeous, almost absurdly so, and sexy; she embodies the kind of woman who routinely makes strong, confident men drop, gasping, to their knees.
Such women need not be beautiful (if they are, so much the better). But they MUST exude sex appeal.
Re. some comparable women . . . let's see, some are beautiful, some sexy, some both; I shan't judge them: Vivica A. Fox, Patricia Heaton, Kirstie Alley (who gives a rat's butt about her weight gain, since Alley is boiling-tar hot?), Mariska Hargitay, Kristin Chenoweth, Vanessa Williams, Leslie Uggamms, Penelope Cruz, Julia Roberts, Jordana Spiro, Mary Stuart Masterson, Ellen Barkin, Jada Pinkett-Smith, Yvonne Elliman -- that's off the top of my head:).
God bless Tia and her family! --
