The Big Bang Theory's touching tribute to Carol Ann Susi was aired on Nov. 13, as reported by E! Online.

Susi was the voice behind the invisible Debbie Wolowitz since 2007. Carol Ann recently passed away at 62 years of age from cancer.

The Big Bang Theory's touching tribute to Carol Ann Susi ended as the show's episode closed with a card that featured Susi's headshot. The message that accompanied the picture read as:

"In loving memory of Carol Ann Susi. 'Mrs. Wolowtiz.' Every time you spoke, we laughed. You're in our hearts forever."

The Big Bang Theory's touching tribute to Carol Ann Susi comes as executive producers for the show, Chuck Lorre, Steve Molaro and Bill Prady released an official unified statement:

"The Big Bang Theory family has lost a beloved member today with the passing of Carol Ann Susi, who hilariously and memorably voiced the role of Mrs. Wolowitz,"

"Unseen by viewers, the Mrs. Wolowitz character became a bit of a mystery throughout the show's eight seasons. What was not a mystery, however, was Carol Ann's immense talent and comedic timing, which were on display during each unforgettable appearance. In addition to her talent, Carol Ann was a constant source of joy and kindness to all. Our thoughts and deepest condolences are with her family during this time, and we will miss her greatly."
