Jennifer Lopez is learning kids grow up so fast … her child Emme Muñiz just graduated high school … and we’ve got pics from the ceremony.

Emme walked across the stage in a cap, gown and lei … accepting her diploma as J Lo stood nearby rocking glamorous sunglasses and an elegant outfit … and beaming with pride.

18-year-old Emme has a twin, Max Muñiz, but he went to a different school … so this celebration was all about Emme … and Max was there supporting his sibling.

Emme chatted with Samuel Affleck at the graduation … Max and Emme became close with Ben Affleck‘s son during their parents’ brief marriage.

J Lo recently opened up about Max and Emme’s plans for the future … revealing they’re both headed off to different colleges.

No word on where Emme and Max are continuing their educations … but J Lo says she plans to send her kids off to school with a ton of stuff … in hopes they’ll realize how small dorm rooms are and come back home. Smart move from the pop star!!!
