Dwyane Wade's best buddies LeBron James and Chris Paul are still on the hunt for an NBA Championship ... but D-Wade's doing just fine with wifey Gabrielle Union.
Gabby and the 3-time NBA Champ soaked up the sun in the South of France Friday ... and Union was totally hamming it up for the camera. Wade -- who just wrapped his 15th season in the league -- acted as Gabrielle's personal photographer while she posed on the rocks and in the water.
Dwyane got in on the photo shoot too, posing for a selfie with his wife of 4 years.
It's unclear if Dwyane will be back for another season ... but by the looks of things, retirement is gonna be pretty sweet.
