Una is the youngest babe, but what she lacks in years lived she makes up for in extensive knowledge of every lip product Kylie Jenner has ever worn. She's dedicated, dogged, and psychotic in the sense that she's forcing us to include a line about how she would die for the Hadid sisters. "NOT figuratively, I mean it literally," she emphasizes. We love her even though she eats her bagels plain. Feel free to send her hate mail about it.
