And while baby Luna seems just a little young for Fashion Week, according to Legend, working around each other's busy schedules to keep the family together has become their No. 1 priority.

"I am tougher with my manager," Legend told ET earlier this week. "Every time they want me to take a trip somewhere I am like, 'Do I really need to go there?' I would rather be at home as much as I can, but obviously you have to travel sometimes for work, so we just try to make it work whenever I leave."
