'We Can't Stop' singer Miley shared the devastating news with her Twitter followers on Tuesday (2 April), saying she felt "broken" by the loss.
Miley tweeted: "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."
Floyd was a familiar face to Miley's millions of Twitter followers as the entertainer frequently posted pictures of herself cuddling up to him.
"I know I don't mean it but I wish he would've taken me with him," she added. "This is unbearable. What am I gonna do without him?
"I am miserable."
Miley, 21, didn't provide any details about what happened to Floyd but did warn tomorrow night's concert audience in Boston that she might not be her usual bubbly self. She's currently on her 'Bangerz Tour'.
The former Hannah Montana star is known for being a huge animal lover and is the proud mum to several rescue dogs.
