Labor Day weekend is upon us, which means summer vacations have officially come to and end, and for children and teenagers alike, it’s time to head back to school. That is, of course, unless you are Kaia Gerber, burgeoning supermodel and daughter of noted supermodel Cindy Crawford. If you are Kaia Gerber, you have some other pressing matters, like launching your new collaboration Karl Lagerfeld, which is exactly what she did this week, bringing along brother Presley Gerber and best friend Charlotte Lawrence. Also this week, Paris Jackson celebrated her later father Michael Jackson’s birthday with Giuseppe Zanotti, and Lili Reinhart took a break from filming Riverdale season three to receive the Variety and H&M Conscious Award at the 4th annual Power of Young Hollywood event. Here, go inside the best parties of the week.
