Thomas Rhett treats his pregnant wife to babymoon

Country star Thomas Rhett has treated his pregnant wife Lauren to a family getaway before they welcome their second child.

The couple discovered Lauren was pregnant in December (16), while on vacation in Tanzania, after already starting the process to adopt a girl named Willa from Uganda, and the 20-month-old officially joined the Rhett family in May (17).

Now Thomas and Lauren are preparing for the birth of Willa's little sister, and to celebrate the occasion, they have taken some time to relax before they become a family of four.

The singer took to Instagram on Monday (10Jul17) to share a photo of two palm trees in a waterfront backyard, and captioned it, "View this week for some family vacation".

Another snap, uploaded on Wednesday (12Jul17), shows the swimsuit-clad parents-to-be posing in the water as Lauren showed off her bulging belly.

"Can't believe we will have a new born (sic) not too long from now," he wrote beside the image, revealing Lauren is currently "36 weeks pregnant".

Thomas didn't reveal where the trio was relaxing, but an earlier post shared by Lauren suggested they had traveled to south Georgia for the mini-vacation.

The Craving You hitmaker will be a busy man this summer (17) - in addition to becoming a father-of-two, he is also in the middle of touring, although he has a two-week gap following a show in Nevada on 29 July (17).

Reports suggest the performance break was scheduled in to allow Thomas a little paternity leave, as the baby is due early next month (Aug17). He is scheduled to return to the stage in Oregon on 17 August (17).
