While Zeta-Jones calls the picture a "throwback," the vacation shot is actually from the star's European getaway from the past few weeks. Along with stopping in Portofino, Italy, the mom of two also visited the French Riviera and did some shopping in St. Tropez with family members during the Mediterranean vacation.
