You know her as:
Dorota, the Waldorfs' Polish maid/housekeeper
Why we like her:
She may be the help, but her nuanced expression, halting English and hilarious one-liners do the impossible: stealing the spotlight from the Queen B. This domestic extraordinaire, keeper of secrets and Facebook user is the perfectly prim and controlled foil needed to deal with Blair's histrionics. No wonder that Basshole covets her.
Where else you've seen her:
As Elzbieta on "The Sopranos" and hopefully soon (if the rumors are correct) on webisodes that reveal the real Dorota.
