Justin Bieber was so tired from making music and preening around the world like a d-bag that he passed out in the studio last night ... on top of Selena Gomez!
A friend snapped a pic on the selfie app Shots ('cause there aren't enough apps that allow one to take selfies), documenting the late night cuddle sesh.
As previously reported, Selena Gomez and Justin Bieber are back together.
Yes, following a couple of ugly splits this year alone, the on-again, off-again, two-person train wreck known as Jelena is coupled up at present and loving life.
Together forever, and ever and ever, or at least 'til next week probably.
Selena's family is worried about the latest reconciliation, and feel it's no coincidence she just threw an all-out house party rager that got the cops called.
