A honeymoon before the wedding? Kaley Cuoco and Ryan Sweeting took a break from planning their upcoming nuptials to enjoy some romantic R&R in the Bahamas this week. The couple jetted off together the night before Thanksgiving -- Wednesday, Nov. 27 -- and have been happily sharing their PDA-filled pictures ever since. 

"Thanksgiving travels w/ my partner in crime," the Big Bang Theory actress, 27, captioned one photo of the pair drinking glasses of orange juice on the plane. Two days later, she posted a shot of her tennis-pro beau on a path by some palm trees. "Hurricane or not we are soooooo in the Bahamas!" she wrote. See more hot celebrity beach bodies, here.

The lovebirds also shared some pictures of themselves at the beach. In one, posted to Sweeting's Instagram on Dec. 2, the shirtless athlete stands ankle-deep in the ocean, wearing just a pair of gray and yellow swim trunks. He's giving a piggyback ride to his fiancee, who has her legs wrapped around his waist and is showing off her slim figure in a black and yellow bikini.

"Not a bad Sunday with my baby," the 26-year-old tennis player captioned the shot.

Cuoco posted a similar picture on her account, but taken from behind to show a tattoo on the small of her back. "#roseisland #bahamas #nofilter," she wrote alongside the photo.

Another picture shared the same day shows the happy couple standing on a dock and kissing.

As Us Weekly exclusively reported in late November, the engaged stars plan to tie the knot on Dec. 31 in Southern California. The event will double as a fire-and-ice-themed holiday bash, complete with cocktails and dancing.
