Miley Cyrus reportedly broke things off with her 20-year-old underwear model boyfriend Justin Gaston last Sunday, according to sources. Miley’s grueling work schedule was said to be the reason for their split.

The Hannah Montana actress had been spotted out and about with her ex Nick Jonas in recent months, and though both have claimed to have had nothing more than a professional relationship, sources say that Justin had been jealous of situation for some time.

Last Sunday Justin wrote on his Twitter, “Haven’t been this miserable in a looong time.. I thought highschool was over.” He’s been Tweeting about bibles and crying his eyes out ever since.
