The actress, who is expecting her first child with hubby Channing Tatum, was snapped walking in a bikini while vacationing in St. Barts on Friday.
In the photo, Dewan-Tatum, 32, sports a playful peach colored bikini top adorned with tassels, and a Theodora & Callum maxi skirt, which shows off her barely-there bump.
Behind his expectant wife, Tatum, also 32, reveals his hunky physique that was only part of the reason he was named PEOPLE's Sexiest Man Alive.
The couple were also spotted the same day strolling on the beach, though both kept covered up during their walk by the water.
Over Christmas, Tatum posted a sweet photo of him cradling his wife's belly.
