TEXAS: Demi Lovato cancelled a photoshoot for The X Factor USA Sunday night after learning that her father had passed away. The judge did not attend the promotional shoot with Kelly Rowland, Simon Cowell, Paulina Rubio and host Mario Lopez following Patrick’s death. Lovato’s older sister Dallas tweeted: “Rest in peace daddy I love you.” The cause of death is still unknown, but Patrick had battled cancer in recent years and pleaded for forgiveness from his daughters last year as his health deteriorated. Lovato previously confessed that she had not been contacted by her father for almost a decade. –DS
