Miley Cyrus and Naomi Campbell had some catching up to do — and forget grabbing a quiet coffee … they had a whole hangout at a fan meet and greet, no less.

Yup, fans rolled up one by one at the London signing for Miley’s new single, “Every Girl You’ve Ever Loved” — feat. Naomi, of course. But the two were so locked in their own convo, they barely threw a glance at anyone.

TBH, it’s kinda brutal … especially after waiting in a monster line, fans got nada. A couple lingered, praying for eye contact — before the photogs ordered them to turn around for the pic.

But for the fans who got snubbed? Total buzzkill — and the internet came in hot, roasting Miley and Naomi for acting like fans were invisible.
