Kyle Richards' youngest daughter, Portia Umansky, is officially in fourth grade and also totally twinning with her pop, Mauricio Umansky. And to prove that theory to be true, her The Real Housewives of Beverly Hills mom posted a snapshot of her daughter looking sassy and just like her daddy.

And, yes in case you were wondering, Portia is very excited to start a new chapter in elementary school, even adding a personalized touch to her school uniform.

That's so Portia!
