A source tells E! News exclusively that the 21-year-old's Alaskan Klee Kai pet pooch was close to 4 years old when he passed away and the cause of death appears to be natural.
"Yesterday was a really tough day," the source explained. "Miley is devastated."
The "Adore You" crooner is set to take the stage on Wednesday evening in Boston and the Bangerz concert is expected to be "very sad."
A giant blow-up version of Cyrus' pup is featured during the show and the source adds that the doll will still be a part of the production.
The pop star sadly informed her Twitter followers Tuesday that Floyd had died and wrote, "Today is the 2nd worst day of my life."
She added, "I don't wanna say it because I don't want it to be real... But my precious baby Floyd has passed away. I am broken." Cyrus shared several pictures of herself with her pet pooch and told her 17.6 million followers, "I know I don't mean it but I wish he would've taken me with him. This is unbearable. What am I gonna do without him? I am miserable."
Cyrus also admitted she may not be in the best spirits at her upcoming show: "I'm sorry in advance if I am not myself tomorrow Boston. I will try my best to be my best."
The blond beauty added on Wednesday, "what you don't understand is he's not in a better place the best place he could be was with me... where he was loved more than anything."
Our thoughts are with you, Miley, during this difficult time.
