There's nothing wrong with wanting to look good. According to her, she's "been spending all day, every day, in weapons training... shooting guns, weightlifting, kick-boxing..."

A-listers aren't just famous for their hard work and talent - they're famous for winning the genetic lottery, they're famous for being in the right place at the right time, they're famous for the privileged starts they had, that allowed them to explore and hone what talent they had and make the necessary connections to get ahead in life.
