The Sisters In That Portal From Facebook Commercial

This is a dumb ad for Portal from Facebook where two sisters are bickering. Yeah, it’s pretty crappy, but the sisters are hot. Anyone know who they are? In a better Portal from Facebook spot, a brother (Arnell Powell) “remembers” his sister’s birthday, but has to improvise a gift. It turns out to be a half-dead plant, and when she points that out, he quips “just like you.” Heh. The sister is played by Shelley Robertson.
