Robin Thicke — Merry Ex-Mas WITH Paula Patton

EXCLUSIVE

Robin Thicke and Paula Patton spent Christmas Eve partying together — and even though they’re not reuniting — based on pics from the bash … some of her family wishes they would.

Robin looked like the most standard guy at the holiday fest thrown at Paula’s household — and her cousin posted photos of the singer all buddy-buddy with everyone in the fam. Except Paula.

A source accurate to Robin tells us it was really normal for Paula to invite Robin because of their kid, Julian. But c’mon — look at the photos — it’s not normal for her family to show him so much like. 

As for Thicke’s current GF April Like Geary – she was NOT his plus one at Paula’s crib. There are limits to forgiveness. Even at Christmas.
