In the Instagram photos, the engaged Big Bang Theory and her friends enjoy some fun in the sun as they live it up in Palm Springs, CA.
Kaley had some of her best gal pals in tow, including her sister Briana Cuoco, Lacey Chabert and Amy Davidson, who posted a picture of the two of them together with Kaley wearing a fuzzy crown and a shirt that said "bride."
The collage, which was shared by Kaley's sis Briana.
While neither Kaley or Amy's posts explicitly said it was Kaley's bachelorette party, the shirt and crown seem to suggest that it probably was.
If not, then these girls just love to have a good time...so good for them either way!
Kaley and her fiance Ryan Sweeting got engaged in September after only three months of dating--but don't worry, their whirlwind romance doesn't mean they're having a shotgun wedding...in fact, Kaley herself took to Twitter to respond to those rumors!
As for the wedding, it sounds like Kaley has some fun surprises up her sleeve (read all about that here).
If the (maybe) bachelorette party is any indication, it looks like the wedding will be a blast!
