LeAnn Rimes plays the doting stepmother as she joins Eddie Cibrian for a family holiday in Mexico

It was exactly a year ago when LeAnn Rimes and married actor Eddie Cibrian were first photographed kissing in a Los Angeles restaurant.

But after splitting from their respective spouses and becoming an official couple, Rimes, 27, and Cibrian, 36, are more than happy to be photographed together.

The country singer enjoyed her first ever family holiday earlier this week with Cibrian and his two young sons as the foursome hopped over the border to Mexico.

Clad in a stripy bikini, Rimes bonded with the actor's sons Mason, six, and Jake, two, as they played in the sand.

Still clearly in the honeymoon period of the romance, the pair couldn't keep their hands of lips off each other as they put on many a public display of affection on the beach.

At one point, they posed for a photo with Rimes's legs wrapped around the former Sunset Beach star.

Rimes was married to dance Dean Sheremet and Cibrian to Brandi Glanville when they were first photographed together last March.

The pair had met earlier that year while filming made-for-TV movie Northern Lights in Canada.

 

The Can't Fight The Moonlight singer initially denied she was involved with Cibrian, but conceded she and her husband were going through a 'difficult time', appealing to her fans to have 'faith' in her.

Cibrian's wife Glanville walked out on him in July, declaring 'Eddie and LeAnn deserve each other.'

The following month, they filed divorce papers, citing 'irreconcilable differences'.

On her website in September, Rimes finally wrote: 'After much thoughtful mutual consideration, Dean and I have agreed to move forward with dissolving our marriage.

'This decision was amicable and we remain committed and caring friends with great admiration for one another. Thank you so much for all of your continued love and support - it is deeply appreciated.'

Rimes married dancer Sheremet in 2002 when she was just 19 and he was 22.
