The couple has mostly kept private about their relationship, not wanting to draw too much attention from the media.

“I”m not trying to hide anything in my life,” Miró explained to Elle.com in March. “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.”

Efron’s next film, Dirty Grandpa, where he stars alongside Robert De Niro, is due to come out on January 22, 2016.
