Pretty Little Liars’ Sasha Pieterse on Medium Tonight!
Rosewood's most intimidating 14-year-old, Sasha Pieterse (aka Alison), will be appearing on the series finale of Medium tonight on CBS. She'll play a teen version of Marie Dubois — the youngest daughter of the show's protagonist — in a flash forward. Let's hope Marie turns out a little nicer than Alison!
Catch Sasha on Medium tonight, January 21, 2011, at 8/7c on CBS.
