Here you go, ladies.  ZAC EFRON and his girlfriend Sami Miro have broken up after two years together.  There’s no word on what happened, but Zac took all her pictures off his Instagram, and stopped following her on social media. Sources said “distance and busy schedules kept them apart, and things just died out” . . . but they’re staying friends. It wasn’t long ago that he was on “Ellen” saying, quote, “Things are great.  She’s awesome.”
