Justin Bieber — Posts and Quickly Deletes Snuggly Pic w/Selena Gomez

0421_bieber_instagramJustin Bieber let his fans know he”s back with Selena Gomez — but only for a few moments — as he 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 we 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.

Posting a pic for the world to see and then deleting could qualify as a “mixed signal.”
