Now, Rauch and Helberg spoke with The Toronto Sun about the huge twist in the lives of their characters.

According to Rauch, she's very excited to have a baby on TV.

"I think what's really great is the writers have always done this fantastic job when any big changes on the show happen. They've always kept the essence of what the show is and it hasn't changed that DNA as a show and it's beautiful how they have done that," she said.

Meanwhile, Helberg said that he believes the writers will be able to present the pregnancy in such a way that will be appealing to fans.

"I think they'll handle it in the beautiful, nuanced way they seem to handle everything. I can't wait to experience the anxiety and the joy and with him," he said in reference to his character.
