Confirmed by Ausiello, though first seen in the show’s titles two episodes ago, Rauch is now a series regular playing Bernadette, the adorably ditzy on-off girlfriend of Howard Wolowitz. She will be a welcome female touch during Kaley Cuoco’s (Penny) absence while she recuperates after breaking a leg in an accident.
Rauch is also known for playing Summer, Hoyt Fortenberry’s girlfriend, in season 3 of True Blood and Tina in the short-lived US remake of Kath & Kim.
But this isn’t the first time a second female character has been added to the line up. Sara Gilbert was made a series regular in season 2, playing Leslie Winkle, Leonard’s friend-with-benefits, but was demoted later that same season. Hopefully Rauch will fare better.
The Big Bang Theory airs Thursdays 8/7c on CBS.
