Jennifer Aniston Covers 'InStyle' March 2012

Jennifer Aniston looks stunning in Calvin Klein Collection as she takes the cover of InStyle magazine’s March 2012 issue.

Here’s what the 43-year-old Wanderlust actress had to share:

On one thing she’d do if she wasn’t an actress: “I’d love to be a dermatologist. I’d be so obsessive about it. I’m fascinated by skin, products, and lasers. I go on the Internet and read all about it. I call it ‘laser porn.’”

On her boyfriend, Justin Theroux: “First of all, he has great style – it’s very specific, and it has been his style forever. Has it influenced mine? No, but I know people say it has. ‘Oh, look, you’re dressing alike.’ And I think, ‘No I’m not. I’ve had this jacket for three years!’

On what she looks for in a man: “Having experienced everything you don’t want in a partner over time, it starts to narrow down to what you actually do want. As I get older I realize what qualities are important in love and what suits me. And what I won’t settle for.”

On what makes her feel young: “You know what makes me feel old? When I see girls who are 20-something, or the new crop of actresses, and think, Aren’t we kind of the same age? You lose perspective. Or being offered the part of a woman with a 17-year-old child. It’s like, ‘I’m not old enough to have a 17-year-old!’ And then you realize, well, yeah, you are. Young? I don’t feel my age. I feel young every day.”
