I think her and Anna Kendrick could easily pass off as sisters

They look somewhat alike but Nikki is prettier.

I think she's much prettier and certainly physically sexier. To me, Anna Kendrick is 'cute-pretty', not beautiful. I don't mean to take anything from Anna . . . but, Nikki really seems to stand out in the crowd, parrticularly when she smiles.

Nikki looks more like Allison Williams.
