Demi had been estranged from her father since 2007, though in recent years Patrick has made several attempts to reach out to his daughter through the press.
In 2011, Patrick Lovato told Radar Online that he had been battling cancer and asked Demi to call him. The same year, her album Unbroken featured the song "For the Love of a Daughter," which was about her tumultuous relationship with her father.
