According to a Hollywood Life insider, the break-up may have officially occurred on December 30 - when the stars had a blow-out in Mexico and Justin returned alone to Los Angeles - but the real problems stemmed from events on December 13.

Because Bieber spent the night with another... man!

“Justin and Nick Jonas hung out all night,” this mole claims, adding that Gomez was devastated over her current boyfriend chilling with her ex: “Selena was crying about it. He wouldn’t even return her calls when she found out and called him up.”

When Bieber and Gomez called it quits previously, the issue at stake was the former's alleged desire to sleep with supermodels.

And the pain of that experience never left Gomez, this source concludes, saying Justin's latest actions "proved he wants to just be a jerk about this and Selena’s sick of being heartbroken... They are finished, and I think it’s for good this time.”

Tear. Big, sloppy, very wet tear, folks.
