Demi Lovato has already spoken out to thank fans for their support following her father’s death, and now the X Factor judge has taken to Twitter with a personal, heartfelt message for her late father.

On June 24, Demi wrote, “RIP Daddy.. I love you.. Love, Your little partner ❤” Included along with the message was an adorable flashback photo showing a toddler-aged Demi sitting happily on her father’s lap.

News of Patrick Lovato’s death first came on June 22, when Demi’s older sister, Dallas, tweeted, "Rest in peace daddy I love you."

Demi and her father’s relationship was not always a smooth one. The two were estranged at various points in the past, and Demi wrote about the experience in her 2011 song, "For the Love of a Daughter." It was reported earlier that Patrick was suffering from cancer, though this has not been confirmed as the cause of death.

Former X Factor co-host Khloe Kardashian, a personal friend of Demi’s, has reached out to show her support. There have also been reports that Demi is leaning on her ex-boyfriend, Wilmer Valderrama, in this difficult time, and that he has become her “shoulder to cry on.”

To quote your music Demi, stay strong. We know that you are unbreakable!
