Kaley and a few select friends travelled to California's Palm Springs to enjoy a girlie weekend of fun, sun and cocktails.
The blonde beauty and her gang, including Kaley's sister Briana and her best friend and former co-star Amy Davidson, posted a string of photos on Instagram.
The main tell-tale sign of a hen party came from Amy's snapshot, where the pair are pictured posing together, beaming from ear to ear. Kaley is wearing a fitted tank top with the word "bride" emblazoned across her chest and what looks to be a fluffy veil.
"#girlsweekend Shenanigans!! I want to go back!!@normancook," Amy captioned the image.
Briana made a special collage of photos to remember the trip, and posted the montage on her Instagram page. Kaley and her friends clearly had a whale of a time, as they're captured relaxing by the pool, drinking cocktails and giggling away.
"Best gals wknd everrrrrr," wrote Briana.
Kaley and Ryan have yet to announce a wedding date, but judging from the photos and their whirlwind engagement of three months, the couple could be tying the knot soon.
"From day one I just knew immediately and it's been magic," Kaley gushed in September. "We have all the same family friends. We grew up with the same people, we just never met.
"So I kind of feel that I've known him my whole life. I know that it seems a little crazy on paper, but it's what works for us."
