Sisters Adira and Olympia Ohanian haven't even hit double digits yet, but the girls have already proven to have a natural talent for applying makeup—and no one is prouder than their mom, Serena Williams.

The tennis legend recently gave Instagram fans a glimpse of her sweet mother-daughter moment with both girls, including footage of Adira using a beauty blender on her mom like a total pro. Williams wrote, "Look at my girls!!!!! The way @adiraohanian handles that sponge though! She's not even 2 yet!"
