Using the Instagram account iputthedistrictonmyback (which 15-year-old Kylie did temporarily use, then switched back to her kyliejenner handle), someone posted (and then deleted) a shot of the Biebs, 18, holding hands with what appeared to be Kim Kardashian's kid sis.
But klearly the Biebs is no kradle robber. Kylie's head was just Photoshopped onto Selena Gomez's body for the snap. (See the comparison above.)
For now, J.B. is up for grabs.
