The Big Bang Theory Cast: Where Are They Now?

Bernadette Rostenkowski-Wolowitz may seem like the sweetest girl you've ever met at first glance, but get on her wrong side and you'll become well acquainted with a voice eerily similar to that of Howard's mother. The similarities between the two Mrs Wolowitzs go far beyond the vocals, of course.

Played by Melissa Rauch, Bernadette became a focal point of the show in later seasons, as she became the only member of the group to give birth not once, but twice (technically speaking, Penny and Leonard had their child(ren) after TBBT ended). The actress behind the character is no stranger to being a mother, having two children in real life with writer husband Winston - daughter Sadie, two-years-old, and son Brooks, just under one-month-old.

Rauch's work following TBBT has so far involved only minor performances due to her maternity leave. She starred in comedy films Ode To Joy and The Laundromat as Bethany and Melanie respectively, along with two episodes of Black Monday as Shira. Rauch's most recent performance came as the voice of Betty Spaghetty/The Nun/Poopsie Unicorn on the stop-motion animation series Robot Chicken.
