It was always going to be an emotional night for Miley Cyrus, with the star breaking down in tearson stage when dedicating a song to her pet pooch Floyd - who died suddenly yesterday (April 2).

Following a string of heartfelt tweets after his passing, the Adore You singer issued an apology in advance to crowds at her Bangerz show in Boston, with the 21-year old taking a moment to remember her pet by dedicating a song to him during her set last night.

The clearly-choked up twerker addressed her fans, saying: "It's gonna be hard for me on this next song. I'm not sounding myself, I don't feel myself. But I just wanna do one song.

"I'm sure you guys already know, but the reason that I'm so upset is my dog, I shouldn't say he was my favourite but he was my favourite, he passed away. I just wanna do a song for him."

Miley went on: "We used to always listen to Fleetwood Mac together, it's his favourite song…so I wanna do this song for Floyd. This song is 'Landslide'."

Despite being very emotional, Mi-Cy managed to finished the song, later taking to Twitter to continue to mourn the Alaskan Klee Kai, writing: "I miss him so much.

"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."

She then posted a screen grab of The Flaming Lips track Feeling Yourself Disintegrate, accompanying the pic with the caption: "Love in our life is just too valuable to feel for even a second without it. But life without death is just impossible."
