A picture posted on Instagram by JUSTIN BIEBER has people thinking he and SELENA GOMEZ may have broken up.

--The photo has Justin looking down.  MAYBE he's being contemplative, and MAYBE he's looking a little dejected.  Then again, he could also JUST BE LOOKING DOWN AT SOMETHING.

--But then there's the caption . . . which is "Lingse".  Nobody knows what that means for sure, but someone figured out that it's an anagram for SINGLE. 

--Justin took the photo down, but as we all know, nothing ever truly disappears from the Internet.  (--Here's the pic.)  (Hollywood Life)
