While the rest of the world has to arrange for day care and babysitters, or wrestle with the decision of whether a parent can afford to give up a career to stay home with the kids, celebs don't have to worry about the issue, since it seems bringing your kid to work is perfectly acceptable in Hollywood.

The girls' eldest sister, 13-year-old Alexia, Luciana's daughter from a previous relationship, sat the excursion out.
