The biological father of Demi Lovato died Saturday, according to a representative of the singer/actress.
According to Us Weekly, Lovato's older sister, Dallas, sent out a tweet Saturday saying, "Rest in peace daddy I love you," and #RIPPatrickLovato later became a trending topic on the social media site.
The 20-year-old singer has yet to comment on her father's death. Her relationship with him has reportedly been distant and sometimes stressful.
In 2011, Patrick Lovato revealed to Radar Online that he was suffering from cancer and that he was trying to get through to his famed daughter.
It has not been confirmed yet if cancer was the cause of Patrick's death.
