The 45-year-old ex-Yankee is kicking off his birthday celebrations early -- on a superyacht surrounded by a gaggle of bikini-clad women.
This will be his first birthday without J Lo by his side in four years, and he doesn't seem to care.
A-Rod couldn't wipe the smile off his face when he was seen slipping down a giant slide while vacationing in Saint-Tropez on Friday.
His breakup has done a body good because the former slugger's six-pack has never been more prominent.
It's hard to look away from A-Rod's shirtless body, but he looked even hotter when wet.
In the photos, he can be seen using his upper arm strength to pull himself out of the water before heading straight to the outdoor shower with some of the women in tow.
J Lo's ex can be seen hosing himself down as the ladies nearby smile in awe.
According to reports, there's no romantic connections on board for A-Rod.
The women are allegedly friends and co-workers. They just happen to be very attractive.
While A-Rod is clearly living his best single life, J Lo's gone IG official with her on-again boyfriend, Ben Affleck.
The Love Don't Cost a Thing singer and the Academy Award winner have been inseparable since she called off her engagement to A-Rod in April.
They've been moving full-steam ahead with their relationship, including making their couple debut on the Gram.
The duo looked pretty cozy when they posed for a photo booth shot at J Lo's bestie Leah Remini's birthday party.
The adorable black-and-white photo immediately went viral, showing Affleck sandwiched between his lover and her best friend.
J Lo and Affleck have already introduced their children and have also been spotted house hunting -- but don't get too excited. Radar is told she's not ready to pull the trigger because she's still financially tied to A-Rod.
