"Big Bang Theory" star Kaley Cuoco is getting ready for her upcoming nuptials with fiance Ryan Sweeting with a couple pre-wedding bashes with the girls.

An all-girls getaway to Palm Springs, Calif., on Nov. 16 included sister Briana Cuoco, former "Bachelorette" star Ali Fedotowsky and "Mean Girls" actress Lacey Chabert.

Her BFF and former "Big Bang Theory" co-star Amy Davidson posted a photo of the beaming bride-to-be smiles in a tank top emblazoned with the word "bride" and a mini veil. "#girlsweekend Shenanigans!! I want to go back!! @normancook," Davidson wrote on her Instagram.

Cuoco, who is keeping her wedding day to the tennis pro under wraps, also posted a picture of what appeared to be a piece of chocolate embellished with the words: "LOVE Kaley + Ryan The SWEETings."

More evidence of the fun came from Briana Cuoco, who competed on "The Voice." Cuoco's younger sister posted a photo collage of the ladies lounging by the pool and sipping cocktails, along with the caption, " Best gals wknd everrrrrr ."

Not ready for the fun to end, Cuoco got the girls together again on Nov. 23 for brunch.

"Holiday brunch! Love these ladies :)," she wrote alongside a group photo.

But all good things must come to an end, and Cuoco posted a photo of herself looking exhausted but happy. She captioned it, "Evidence of a great day :)"
