Demi Lovato has thanked fans for their support following the death of her father.
The singer and actress's dad Patrick passed away at the weekend.
She tweeted: "I feel so humbled to have had so much support from my fans, friends, family and complete strangers... God bless you all, thank you so much."
Demi, 21, was thought to have had an up and down relationship with her dad, and referenced their difficult relationship in her 2011 song For The Love Of A Daughter.
The star pulled out of an X Factor USA photo shoot after learning the news. She had been due to join fellow judges Simon Cowell, Kelly Rowland and Paulina Rubio to promote the next series of the US singing competition.
Simon tweeted his condolences, saying: "My thoughts are with you Demi. X."
X Factor USA host Mario Lopez shared a photo of the event, showing the other judges. He wrote: "With my @TheXFactorUSA team! Missing @ddlovato today... :(."
