The High School Musical star and model, both 28, have been dating since the fall of 2014, but PEOPLE can confirm the relationship is over.
Efron removed all photos of Miró from his Instagram and stopped following her on both Instagram and Twitter. So far, Miró continues to follow Efron on social media.
While Efron's been busy filming the Baywatch remake in Tybee Island, Georgia, sources tell PEOPLE the actor has been returning home to L.A. every weekend to spend time with Miró.
The former couple was last spotted food shopping together at an L.A. supermarket on April 11. Miró later attended Coachella without Efron over the weekend, where she was seen attending the Nylon, Calvin Klein and Jeremy Scott parties. On Friday, she tweeted "Donde estas mi amor" (Where is my love?) from the music festival.

Efron gushed over his relationship with Miró during a recent appearance on The Ellen DeGeneres Show, telling the host, "Things are great. She's awesome."
The Neighbors 2: Sorority Rising star melted hearts on his first anniversary with Miró back in September when he tweeted, "Happy anniversary baby. I love you. September 5th." Miró later responded, "Time flies when you're having fun. Happy anniversary baby. I love you too."
Speaking about dating a high profile celebrity, the model had told 'Elle.com", "I've never spoken about us before, but, um, it's definitely different."
She added, "If I was dating someone who wasn't in the limelight, I might have more photos on [Instagram] of our relationship, but I do think it's important. I mean, it's what is going on in my life, and I think that my social media can still represent that."
