“Big Bang Theory” actress Kaley Cuoco is already feeling the holiday spirit, but co-star Johnny Galecki might not yet be on the same page.

On her Instagram account, the actress shared a hilarious photo of herself and Galecki outside the Warner Bros. studio. The two cast members are about to film a new episode for their sitcom when Cuoco decided to pose while wearing her Christmas-inspired sweatshirt. The actress also had a huge grin on her face as she raised both arms up in the air to show her excitement. Galecki, on the other hand, was wearing an all-black ensemble and a smug look on his face.

In the caption, Cuoco made a sarcastic joke about how Galecki seemed to be having so much fun in the snap.

Meanwhile, the 31-year-old actress also posted a short behind-the-scenes video from the set of “Big Bang Theory” Season 10. The clip revealed that everyone on set is already on a festive mood. One of the staff was featured lip-syncing Mariah Carey’s hit song, “All I Want For Christmas Is You,” while cast members Melissa Rauch and Mayim Bialik looked on. There was also one staff wearing a Santa hat and beard. In the clip, everyone was laughing and appeared to be having a lot of fun, which prompted Cuoco to say that she loves her work so much.

In other news, “Big Bang Theory” Season 10 will air a new episode on Thursday, Dec. 15 before the sitcom officially goes on a short hiatus. In “The Birthday Synchronicity,” Bernadette (Rauch) will be giving birth to her daughter, Hallie. Amy (Bialik) will also be celebrating her birthday, but it seems that Sheldon (Jim Parsons) won’t prepare anything special for her. Last year, the couple had sex for the first time with each other. But this year, Sheldon and Amy won’t have coitus, and Amy won’t necessarily be pleased with this.

Catch the gang when the next episode of “Big Bang Theory” Season 10 airs on CBS on Thursday, Dec. 15.
