Madonna and her 15-year-old daughter Lourdes have more in common than good genes: They currently have a junior fashion line for Macy's called Material Girl. The duo, who launched the line in 2010, recently announced that fellow rock royalty Georgia May Jagger (daughter of Mick) would be the spokesmodel. "Family is everything. Family comes first. It's not what I expected it to be, but nothing ever is," says the 53-year-old singer, who is also mom to Rocco, 11; David, 7 and Mercy, 6.
