Demi Lovato's dad dies; Patrick Lovato was estranged from daughter
News broke when Demi's older sister Dallas tweeted on Saturday (June 22), "Rest in peace daddy I love you." Demi's mom Dianna de la Garza added, "Thank you for the outpouring of love and prayers. Y'all are amazing."
Demi herself is so far mum about her father's death -- the two had a strained relationship.
Demi told the New York Daily News in 2009 that they hadn't spoken for two years -- "When somebody lets you down after you've been the only one there for them, and so many times, you don't know what else to do. I had to cut off all connection. I didn't know what else to do."
There is no official word about Lovato's cause of death, but he told Radar Online in 2011 that he was battling cancer, but had spoken with Demi during her time in treatment for bipolar disorder.
