Justin Posted (and quickly Deleted!) a photo of him and Selena
JB posted a pic of himself getting cozy with SG ... and then quickly deleted it.
Gomez sparked reunion rumors when she jetted off to Norway to meet up with JB, who is touring there.
As TMZ previously reported ... Selena and Justin have seen each other periodically since breaking up at the end of 2012. We're told he's been "tortured" because she's been giving him mixed signals.
