Heidi Klum and Denise Richards' daughters might have a little bit of an advantage over their fellow Brownies when it comes time to unloading Thin Mints and Samoas.

Yesterday, Klum helped Leni, 7, sell Girl Scout Cookies in L.A., and earlier this month Richards did the same with her 8-year-old daughter Sam.

Today the organization is celebrating a major milestone: turning 100 years old!

Throughout Girl Scouts' century-long history, many stars have earned their badges and adhered to the Scouts' "Be Prepared" motto. Dakota Fanning, Lucille Ball, Sheryl Crow and Mariah Carey are among those who've donned those iconic sashes.
