When season eight of "The Big Bang Theory" returns, Penny and Leonard will still be the happy, newly engaged couple. However, there won't be much wedding planning anytime soon.

"The Big Bang Theory" showrunner Steven Molaro recently told TVLine that Penny and Leonard are the kind of people who would want to enjoy being engaged before getting hitched.

"I can't say for sure, but I doubt it," he shared when asked about Penny and Leonard's wedding. "They're in a great place. They're the kind of couple where they can be engaged for a while and that's fine."

Molaro also added that Penny will be too busy with her new career, which will put the wedding on the backburner. And because she is good at what she does, Penny is going to immensely enjoy her new job as a pharmaceutical sales representative.

"Whether she realizes that yet or not," Penny is well suited for the job, said Molaro, adding: "She's cute and flirty and gets along with people, and she's great at memorizing lines. This is a job that will fit her personality and talents well."

However, this is expected to cause a strain in her relationship with Leonard, as Penny will now be earning much more than what she made as a waitress at the Cheesecake Factory. The relationship dynamics are going to change, and this will be highlighted when the season premieres on Sept. 22.

"In the first episode back, she will embark on a brand new career, and that will be taking up a lot of her time and energy. Bernadette has helped to get her a job as a pharmaceutical sales rep at her company. She is going to put her failed acting career on the backburner for a while," the executive producer shared.

Production of season eight started in the second week of August, after a short delay owing to issues with the contracts of Jim Parsons, Johnny Galecki, and Kaley Cuoco. Production resumed only after each of the three leads was promised $1 million per half-hour episode.

Speaking about the issue, Parsons, who played Sheldon Cooper, told Entertainment Weekly that he had hoped the issues would be sorted out much before the production was initially slated to start.

"I always thought everything would be worked out by the start date. When it wasn't, it certainly wasn't a good feeling, but there was absolutely no getting around the fact that everything had to be dealt with and finished before we could get back."
