The former Yankee and the Love Don't Cost a Thing singer both got the hell out of Dodge to celebrate their July birthdays and somehow ended up at the exact same place -- St. Tropez.
In brand new photos, A-Rod showed J Lo that two can play the game of PDA.
The Hustlers actress made headlines with Ben Affleck after photos circulated showing his hands all over her while onboard their $130 million yacht.
A-Rod had a yacht of his own but managed to sneak away secretly to peek at J Lo's.
In the photos, the ex-MLB player can be seen whizzing right by his former flame's superyacht on a jet ski with Collins straddling him from behind.
The duo can be seen smiling as they passed J Lo's vessel earlier this week.
Despite having his life vest on, A-Rod's chiseled arms were on full display.
As for Collins -- who is only 35 -- she slipped her perfect curves into a tiny string bikini and jumped on the back of A-Rod's jet ski for the run ride.
Despite claiming they are "just friends," A-Rod and Collins look pretty cute and cozy together.
As Radar reported, J Lo escaped to the French Riviera with Affleck to ring in her 52nd birthday.
Not only was she sporting a itty bitty bikini of her own, but she was also rocking a giant diamond ring.
J Lo and Affleck ended up in St. Tropez just one day after A-Rod set sail on the same sea.
The ex-slugger turned 46 years old on Tuesday, just three days after his ex's birthday.
This is the first time they haven't celebrated together in four years, and it appears both are doing just fine with their replacement party partners.
Not only is A-Rod in France with Collins, but he's also added Jessie James Decker and her husband, retired NFL player Eric Decker, to the mix.
