It appears that Amy Farah Fowler isn’t going anywhere.
That’s because Mayim Bialuk has been promoted to a series regular on CBS’s hit comedy “The Big Bang Theory.” Bialuk began playing the role in last year’s season finale and has been featured in several episodes this year.
Joining Bialuk as a series regular is Melissa Rauch, who plays Howard’s romantic interest Bernadette.
Both actresses will be regulars for the rest of season four. However, this doesn’t necessarily mean they’ll appear in every episode going forward.

Hooray for the lady geeks!
More Shamy? That is awesome!
Good news!
Very smart move on CBS’s part. She has added very impressive numbers to the ratings and is a perfect estrogenic-Sheldon.
