The pop star performed Twinkle Song, which is an ode to some of her late animals, on the piano as she gazed at heart-shaped pictures of her dead dog Floyd, a cat and her pet fish Pablow.

As she reached the end of the song, she started to cry.

Miley was left devastated when her pet husky was killed by a coyote in April, 2014.

She tweeted: "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?"

Otherwise, Miley's appearance on the SNL season premiere was all laughs - she appeared in skits as a hardcore rapping high school sweetheart and as The Parent Trap star Hayley Mills, and show regular Kyle Mooney got a taste of what life would be like as the singer's husband and father to her son, Six Flags, as he contemplated marriage to Miley.
