The 47-year-old singer and 48-year-old Latin music star rang in son Max and daughter Emme's 9th birthday with the kids' godmother, actress Leah Remini, her husband, actor Angelo Pagan, and other friends.
"Celebrating our Max & Emme's 9th birthday @jlo @marcanthony @therealangelopagan #familia #memories #friendship," Remini captioned a photo of herself with Lopez, Anthony and Pagan on Instagram.
Max and Emme officially turn 9 years old on Wednesday. Lopez said in an interview with People and Entertainment Weekly in March 2016 that her children inspired her 2011 hit single "On the Floor."
"I had given birth and the kids honestly just gave me a new direction," the star shared through tears.
"They just made me realize, like, what was real and what wasn't real," she added. "They just changed everything."
Lopez and Anthony split in 2011 after seven years of marriage, but have remained close friends since. The "I Luh Ya Papi" singer was last linked to rapper Drake, but confirmed she's single on Monday's episode of The Ellen DeGeneres Show.
"She says she's single at the moment and too busy and doesn't have time for first dates," DeGeneres announced.
Anthony, meanwhile, appears to be dating 21-year-old model Mariana Downing following his split from wife Shannon De Lima. Sources told Page Six last week that the Latin music star and Downing are "inseparable."
