Asked whether she has any "hidden beauty talents," Mary-Kate Olsen told ELLE that she's actually a amateur and that she never really brushed her own hair.
"You know, the truth is I feel like I just learned how to brush my hair like last week!" she joked.
It might also have something to do with the fact that Mary-Kate and her twin sister, Ashley, have been media moguls since they were toddlers.
“We were designing clothes for ourselves as we were so petite,” Mary-Kate said. “So I think that is when we became obsessed with fit, and now the obsession has become a profession.”
