After last night's dizzying spectacle at the Oscars, let's talk about someone who really defines the word "star". As a kid, I remember vividly Life Magazine's 1972 cover of Elizabeth Taylor reaching her milestone fortieth brithday, and glimpsing what glamour really meant. This week, incredibly, Liz turns 77. For those who know her mainly from those recurring news stories about her health problems (she has broken her back several times and endured three serious bouts of pneumonia), her fluctuating weight, an unlikely friendship with Michael Jackson, or her fabled eight marriages (she wed Richard Burton twice), you may want to pay extra attention.
