Betty Grable
AGE 27 1943

Jennifer Morrison
AGE 29

While posing as popular World War II pinup Betty Grable, House star Jennifer Morrison felt "a little bit of pressure," she says. "Her body is beautiful. There's no way anybody today would not say she's incredibly sexy. I have a lot to live up to." Luckily, her athletic lifestyle works in her favor. "I've always been active physically," says Morrison, a former dancer who recently added boxing to her workout rotation. Just don't ask her to start counting calories. "I'm very lucky. I don't put rigid restrictions on myself," she says. "At one point I'm going to reach an age where my metabolism does not run at the rate that it does and I will not be able to eat a bag of Cool Ranch Doritos whenever I want. So I figure I should enjoy it while I have it!"
