"What's great is that when you're older and sexy, you're not really just a one-trick pony," Alba explained. "There is so much more that goes along with it. Intelligence is sexy, confidence is sexy, knowledge is sexy. At work, I'm wearing a completely different hat. It's a pretty creative environment, but there's a lot of data and analytics, a lot of boring meetings, just straight business stuff. It's cool, though!"
