France is one popular vacation destination.
Lopez, who turned 52 on Saturday, traveled to the European destination to celebrate her birthday with boyfriend Ben Affleck. Meanwhile Rodriguez, who turns 46 on Tuesday, also made the trip to celebrate his big day.
"He's with family and friends and people he works with," a source previously told PEOPLE of the retired baseball player, whose engagement to Lopez ended in April. "He's doing great and celebrating his birthday and Minnesota Timberwolves sale."
Lopez celebrated her 52nd birthday on the water, sharing a steamy kiss with Affleck, 48, aboard a yacht before heading to nightclub L'Opéra where they celebrated with an intimate group of friends.

"5 2 … what it do …" the singer and actress captioned some photos of them. Although her pal Leah Remini previously posted a photo of them at her birthday party, it was the first time the lovebirds shared a glimpse at their relationship on their own social media accounts.
Lopez and Affleck originally began dating in July 2002 after filming Gigli together. They got engaged that November before postponing their September 2003 wedding, just days before the date, and ultimately calling off their engagement in January 2004.

"New energy is emerging. New levels are unlocking for me mentally, physically, and spiritually," he added. "I am remaining patient and know that this new phase of my life is coming."
