This is not OK.
Such sad, sad news!
We hate to report it, but it seems Demi Lovato's biological father, Patrick Lovato, has passed away.
We have very minimal details about the death, but her sister, Dallas Lovato, broke the news over Twitter.
Rest in peace daddy I love you..

We know Demi wasn't super close to her biological dad, but we can't imagine how hard this is on her.
We hope the whole family has strength during this difficult time.
Our thoughts are with all of them!
