Gwyneth Paltrow and Chris Martin had a reunion of sorts this week … all to celebrate their daughter’s college graduation.

Apple got her diploma from Vanderbilt University in Nashville … after majoring in law, history, and society. Smart (organic, gluten-free, grain-free, vegan) cookie!

The movie star and rocker share two kids … Apple and her bro, Moses — and the pair have said over the years they’ve maintained a friendly relationship since their split in 2014. Still … it’s rare to see them together out in public.

Gwyneth attended the ceremony with hubby Brad Falchuk … while Chris was snapped chilling with Moses.

Earlier this year, Apple told Vogue … her initial plans to go to law school had changed … and she was ready to follow in mom’s footsteps, adding … “I love dancing and I love acting. My dream is to act.”
