Kaley Cuoco showed off her bikini body while vacationing with her athlete fiance, Ryan Sweeting. "The Big Bang Theory" star basked in the sun in Bahamas recently.

According to the Huffington Post, the 28-year-old blonde starlet and Sweeting, 26, enjoyed some rest and relaxation with her love over the weekend.

The pair took to Instagram to post photos from their beach trip. Sweeting's images showed the CBS comedy actress rocking a mismatched two-piece as she took a dip in the water with her shirtless future husband. 

"Not a bad Sunday with my baby @normancook #roseisland," wrote the tennis player on Sunday.

The starlet, who plays alongside Jim Parsons, Johnny Galecki, Melissa Rauch and Mayim Bialik on the hit show, also mentioned the romantic rendezvous on the social site.

"Dream vaca w my love @ryansweething #nofilter," posted Cuoco. 

The twosome had confirmed their engagement in late September. They had only dated just three months, but the actress admitted that she knew Sweeting was the one from the moment that they met.

"From day one I just knew immediately and it's been magic," said Cuoco to "Entertainment Tonight." "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."
