Kaley Cuoco recently forgot to bring her glasses to the set of “Big Bang Theory” Season 11.

On her Instagram account, the actress shared a photo of herself sitting on Sheldon Cooper’s (Jim Parsons) famous sofa and reading her script. Since the actress wasn’t wearing her eyeglasses at the time, she placed a flashlight on her forehead so she could make out the words. In her caption, Cuoco joked about not being able to see.

The “Big Bang Theory” star, who plays the role of Penny, sometimes shares photos of herself at home wearing her eyeglasses. But when the cameras start rolling, Cuoco likely wears contact lenses to help her see clearly.

Cuoco and her CBS co-stars are currently filming the upcoming episodes of “Big Bang Theory” Season 11. By the looks of it, they are already shooting the third episode of the upcoming season. According to a fan-made spoiler account, the installment is called “The Relaxation Integration” and will center on Sheldon struggling to pick his and Amy’s (Mayim Bialik) wedding date.

Even though the title and synopsis of episode 3 haven’t been confirmed yet, it’s possible that Amy will give Sheldon a resounding yes to his proposal when the show premieres. After all, Amy has been madly in love with Sheldon for the past couple of years and has wanted him to propose to her for a while now.

But the bigger question regarding the premiere is whether or not Sheldon will come clean to Amy about kissing Ramona (Riki Lindhome). It was clear that she was the one who made a move on him, and Sheldon somewhat rejected the kiss. But this admission could still cause a strain on the couple’s relationship.

Meanwhile, another interesting storyline from Season 11, as revealed by the same spoiler site, focuses on Bernadette (Melissa Rauch) and Howard (Simon Helberg). The two could be expecting their second child in the show since Rauch is pregnant in real life. This will be explored in the premiere, rumored to be titled “The Proposal Proposal.”

“Big Bang Theory” Season 11 will premiere on CBS on Sept. 25 at 8 p.m. EDT.
