Kaley Cuoco was bumping along on Wednesday afternoon while on the Los Angeles set of her upcoming Peacock series, Based An A True Story.

The pregnant actress, 37, was spotted strolling in and out of her trailer in a baggy black tee and pink tie-dye sweatpants.

She rocked a blue Adidas track jacket that matched the slide sandals on her feet.

During a lull in filming, Cuoco picked up some boxes of Dunkin Donuts and a plastic bag filled with goodies.

The Big Bang Theory star - who will appear in a Super Bowl pregame advertisement - revealed last year that she is expecting her first child with boyfriend Tom Pelphrey.

Though she was noticeably dressed down for the afternoon shoot, Cuoco's golden blonde hair looked professionally styled in voluminous ringlets.

She accessorized with aviator shades and stayed hydrated with a water bottle.

As the day progressed, Cuoco eventually tied her locks up into a tight bun.

Cuoco and her actor beau Pelphrey have been together for nearly a year.

Prior to the Ozark star, Cuoco was married to equestrian Karl Cook. She and Cok wed in 2018 but would split in 2021.

Her first husband was tennis star Ryan Sweeting. They were married from 2013 until 2016.

Cuoco found love again with Pelphrey in early 2022 and they went public with their romance that May. The couple had met through the actress' agent. 

After less than a year together, Cuoco announced in October that she was pregnant.  

She later revealed that they would be welcoming a girl. 

The actress recently opened up about her pregnancy to Entertainment Tonight and admitted she's not much of a 'prepper' like some women.

'I have no plan and I've read zero books so that's the type of mom I will be...I'm not like a prepper. I'm just not that way. It's gonna be great, I trust the process,' she said.

Cuoco also expressed that her mother is awaiting the day she officially becomes a grandmother.

'My mom is amazing. She has honestly been waiting on a grandchild for, like, 20 years. So she's absolutely thrilled,' she told the outlet.

She also discussed Based On A True Story and revealed that filming during her pregnancy has been a surprisingly easy process.

'The show is so funny and so wacky and so strange and the best part about it for me is I get to be pregnant, eat whatever I want, wear like the most comfortable clothes, everyone treats me like a queen,' Cuoco explained.

Cuoco leads the comedic thriller series, which will land on Peacock sometime in the near future
