'The Big Bang Theory': Huge Developments For Sheldon And Amy [Spoilers]

The Big Bang Theory is officially preparing a huge present for the series' fans and for Sheldon losing his virginity!

According to ET, who spoke to the cast of The Big Bang Theory ahead of Season 9's return on December 10 at 8 p.m. ET, Sheldon Cooper and his beloved Amy Farrah Fowler are going to have sex this season.

Sounds hard to believe, right? That's exactly what Jim Parsons, who plays Sheldon on The Big Bang Theory, said. So apparently, after five years of dating and going through a devastating break-up, Sheldon and Amy are going to finally have sex, as revealed by the actors and showrunners in an interview with ET.

Speaking to ET, The Big Bang Theory's star Parsons was already coming up with jokes about the intimate moment between the couple.

"Putting the 'bang' into the theory, I guess."
That comment alone made Mayim Bialik, who plays Amy on The Big Bang Theory, burst into laughter, as seen in the video provided by ET.

However, both Parsons and Bialik were surprised to find out about the upcoming highly-anticipated scene on The Big Bang Theory. Parsons revealed to ET that he was stunned.

"I was very surprised. But then I read it, and it seemed absolutely the right time."
The intimate scene between the duo will happen in The Big Bang Theory's episode that airs on December 17, according to the Hollywood Reporter. In the episode, it's Amy's birthday, and sex is the present Sheldon has come up with. And it's sure to be the most memorable birthday present Amy's ever received.

But The Big Bang Theory fans are not particularly surprised over the upcoming sex scene between Sheldon and Amy, because despite the fact that the series started off as a brainy comedy with geek-ish jokes, over the past nine seasons, the show has shifted toward a romantic comedy.

But it doesn't mean that the intimate scene will change anything about The Big Bang Theory. Parsons promises that it will not put an end to the show's signature style of balancing comedy and compassion.

"It was fun to act. It wasn't hard to act."
Bialik added that it wasn't "icky" to act either, and Parsons, who has won four Emmy awards for The Big Bang Theory, agreed.

But it's not all that The Big Bang Theory is preparing for its fans. According to the Hollywood Reporter, Bob Newhart is returning to the series as Sheldon's spirit-form life mentor. Apparently, he will be the one to push Sheldon to make possibly the most important decision in his life.

Fans of Star Wars, rejoice! The upcoming season of The Big Bang Theory will have Sheldon, Leonard, Howard, and Raj get tickets to see Star Wars: The Force Awakens, the premiere of which (in real life) opens just a few hours after the CBS comedy's episode is aired.

In an interview with the Hollywood Reporter, the showrunner of The Big Bang Theory – Steven Molaro – revealed that he had been thinking of introducing the intimate scene between Sheldon and Amy earlier in the show. And, according to him, he has always had the idea of having Bob Newhart's character help Sheldon to make the crucial decision.

"With the idea of Newhart and the Star Wars release coming up, it started to gel. The fact that we were able to find a way to blend Star Wars with something for us on Big Bang — it's such an event for Sheldon and Amy, I couldn't be happier with it."
Meanwhile, Bialik has recently revealed what it was like when she first joined the cast of The Big Bang Theory in Season 4, as reported by Design & Trend.

The actress revealed she felt like "a high school newcomer" who came to the set where everybody knew one another. But that wasn't an issue because the CBS comedy has a "very welcoming cast."

"We have a very welcoming cast. Melissa Rauch and I made fast and good friends with everybody. Now that we're in season 9, it's like I hardly remember what it was like to come in, because we'll all just been here so long."
