Actress from the latest episode..?

I put the question mark because it was the first episode i've watched and i'm not sure if it was new or not. It appeared this week, I believe on either Tuesday or Wednesday? I'm not sure which day it was out of the two.

Anyway, the actress, who was brunette, played a sort of ditzy nympho who was dating the younger brother Ben. Ben was trying to have intellectual conversations with her, but she was always spacing out and referring to sex with everything.

Does anyone know this actresses name? Any information would be appreciated, she was really beautiful!
