We've learned J Lo and Affleck's trip is actually a twofer, with the duo agreeing this would be the perfect opportunity to showcase their on-again relationship to the world.
The Love Don't Cost a Thing singer even brought her entire team to make sure their PDA parade goes off without a hitch.
Radar is told not only is the couple traveling with a professional photographer to capture all of their sweet moments, but they also brought along J Lo's manager, and not one, but two publicists.
The couple's plan has gone on without any issues thus far. J Lo's team even helped her avoid an awkward run-in with her ex-fiancé Alex Rodriguez.
Oh! Did we forget to mention the ex-Yankee is in Saint-Tropez too?
J Lo and Affleck have been frolicking all over the ritzy coastal town and have narrowly missed bumping into A-Rod on several occasions -- but thanks to the singer's dream team, that hasn't happened ... yet.
While Affleck can't keep his hands off J Lo, the former MLB star isn't sitting around idle.
A-Rod dangled NFL presenter Melanie Collins right under J Lo's nose when he whizzed right by her $130 million mega-yacht on his jet ski with the gorgeous blonde.
A-Rod had a yacht of his own but managed to sneak away secretly to peek at the Hustlers actress' massive sea vessel.
The ex-baseball player looked pretty cozy with Collins -- who is only 35 -- as she straddled him in her itty bitty bikini, despite the two rumored to be "just friends."
J Lo celebrated her birthday in style with Affleck on July 24, but she wasn't the only one in Saint-Tropez partying for her special day.
A-Rod turned 47 years old just three days later.
This is the first birthday they've celebrated without each other in four years.
J Lo famously called off their engagement in April and has been inseparable with Affleck ever since -- something tells us Collins is helping A-Rod take his mind off their breakup.
