How cute are Knox and Vivienne Jolie-Pitt?!

On Sunday we snapped Brangelina's twins shopping with their manny in Los Angeles, and we can't believe how fast they're growing up!

Vivienne wore a pair of combat boot-inspired Converse shoes and tights, and we couldn't help but notice the fake tattoos covering her arms. Like mother like daughter?

Back in 2011 Knox and Vivi's big sister Shiloh was photographed with a temporary tattoo on her leg, and when asked about her middle daughter's funky style, Angelina told Reuters, "Children should be allowed to express themselves in whatever way they wish without anybody judging them because it is an important part of their growth. Society always has something to learn when it comes to the way we judge each other, label each other. We have far to go."

But at what age would mom let her little ones get the real thing?
