The Big Bang Theory star spent Thanksgiving with her beau in Florida last Thursday (28 November) before jetting off again for some fun in the sun in "paradise", as Ryan wrote on his Instagram page.
And it looks like the soon-to-be newlyweds are having a great time together, lapping up the warm weather and putting on lots of public displays of affection.
Kaley, 27, posted a cute photo of herself kissing Ryan on a dock and wrote: "Dream vaca w my love @ryansweething #nofilter".
Meanwhile, tennis player Ryan uploaded a candid snap of himself giving Kaley a piggyback in the sea and added the caption: "Not a bad Sunday with my baby @normancook #roseisland".
The couple also posed for a photo by the sea shore, with Kaley showing off an eye catching Chinese tattoo on her lower back, and had lots of laughs going tubing with each other at their resort.
Although Kaley and Ryan have only been engaged since September, they are already eager to take the next step and tie the knot as soon as possible.
Last month, Us Weekly reported that the happy couple are hoping to marry on New Year's Eve (31 December) in California, which gives them less than four weeks to finish their planning!
