The "Baywatch" actor, 28, seems to have purged all pictures of the 28-year-old model from his Instagram and Twitter. He also unfollowed her, but as of Monday afternoon she was still following him.
The two were seen out grocery shopping together in L.A. two weeks ago, reported People, which said it had confirmed the split. Though he's been filming the lifeguard-movie remake in Georgia for a couple of months, he was coming home on weekends to see her, the outlet said.
On Friday, Miro posted a picture of herself solo taken at a Coachella party with the caption, "Donde estas mi amor," or, "Where are you my love."
Efron was enthusiastic about his future ex-girlfriend back in January when he sat down with Ellen DeGeneres to promote "Dirty Grandpa." "We get to do cool stuff ...," he said after gushing about her. "We do a lot of adventurous stuff together. When I'm not working we hit the road."
Now it looks as if he's hitting the road alone.
