On the prowl again? It looks like Zac Efron might be back on the market.

The insanely ripped "Baywatch" star is rumored to have broken up with this girlfriend of nearly two years, model Sami Miro. The proof? Instagram.

Over the weekend, Zac reportedly deleted every photo of Sami from his Instagram account.

Ouch!

Among the casualties are photos of Zac and Sami's November vacation to Japan and Vietnam. There was also a picture in which he appeared to be faking a proposal. That, too, is gone.

Zac also unfollowed the 28-year-old on Instagram and Twitter.

The only picture of her existence that remains on his page is a photo of him in front of a painting that she apparently gave him several months ago. Many pro-Zac folks have left biting comments about that still-existing snap, many of them skewering Sami.

On Monday, Us Weekly reported that the two are officially dunzo, too.

No official word has been released about the status of the relationship. However, a scandalous report from Hollywood Life implies that Sami cheated on the "Neighbors" star during Coachella.

Over the weekend, the hunky actor posted a photo to Instagram of himself on the "Baywatch" set looking off into the distance from a lifeguard shack.

"It's not who I am underneath...but what I *do*...that defines me," he cryptically captioned the photo.

Miro first spoke about their relationship during a March 2015 interview with Elle.com.

"I've never spoken about us before, but, um, it's definitely different," the model said of being in the public eye. "I think that you have to take that [kind of attention] with a grain of salt, and put yourself in other people's positions. I think that's actually a really big part of it, putting yourself in their shoes, and trying to understand where they're coming from, and then it kinds of makes sense."

In September she took to Instagram on the couple's anniversary to gush about him.

"Time flies when you're having fun," she said of a pic of the two of them. "Happy anniversary baby I love you too @zacefron September 5."
