Zac Efron [1] and Sami Miró have called it quits after almost two years [2], Us Weekly reports. Just before the news broke, Zac deleted all of his Instagram snaps with Sami [3], a telling sign that their relationship was on the rocks. The couple first emerged hand in hand [4] way back in October 2014 and most recently cuddled close at the MTV Movie Awards [5], which swept through LA earlier in April. It's sad to see the lovely couple go, and even sadder to see this year's long list of celebrity breakups [6] growing just a bit longer.
