Kaley Cuoco basked in the Bahama sun as she enjoyed a little rest and relaxation with her fiance Ryan Sweeting over the weekend.

In pictures posted by Sweeting, the "Big Bang Theory" star rocked a mismatched bikini as she took a dip with her shirtless beau.

"Not a bad Sunday with my baby @normancook #roseisland," the tennis player wrote on Instagram Dec. 1.

Cuoco also posted some photos on her own Instagram account, writing, "Dream vaca w my love @ryansweething #nofilter."

Cuoco, 28, and Sweeting, 26, confirmed their engagement on Sept. 26 after just three months of dating. Although their courtship was short, the actress admits she knew Sweeting was the one from the minute she met him.

"From day one I just knew immediately and it's been magic," Cuoco told "Entertainment Tonight" of their romance. "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."
