Now this is the look of love!
The crooner, who was wearing a Valimare bikini, is shown snuggling up to the handsome actor during a romantic Hawaiian sunset on the beach.
"Happy Hawaii! Yep another lovey dovey bikini photo #moretocome," she captioned the picture on Twitter.
The loved-up duo has been enjoying their sun-filled vacation over the last few days.
Over the weekend, Rimes was spotted getting surfing lessons alongside Cibrian and working on her tan.
The Cibrians are in Hawaii to film their upcoming VH1 reality show, tentatively titled LeAnn & Eddie.
During a recent appearance on Jimmy Kimmel Live, Cibrian explained that the program will give viewers an unparalleled glimpse into the couple's everyday life.
"I mean, we looked at each other and we like, we saw the majority of reality shows, the castmembers get to consume a lot of alcohol and then they get to fight and throw things and we looked at each other and we said, 'Why don't we do that? That sounds like fun. Let's join ‘em.'"
"I think this reality show could turn out to be a terrible, terrible idea," Jimmy Kimmel told Cibrian with a laugh.
"Well yes, it probably will, it probably will," Cibrian replied. Uh-oh…
Well at least it looks like things are going smoothly so far!
