Looks like Demi is making it Insta-official with a cute pic of a new mystery man. She posted a surprise mirror selfie getting cozy with a guy covered in tattoos and captioned it "My heart."
Keep in mind that this is purely speculation because neither one actually comes out and states that they're a couple, but there are photos like this on both of their accounts.
Based on his caption, I think it's pretty safe to assume that these two are more than friends.
While he seems to be a mystery, it is certain that he is a 25-year-old model.
There's little known about him beyond that, but if the two keep sharing pics like this, surely the truth will come out soon.
