Miley Cyrus has been left heartbroken following the death of her beloved pet pooch Floyd.

The Adore You singer took to Twitter to break the sad news to her fans, writing: "Today is the 2nd worst day of my life…

"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."

She continued: "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…"

The star, who is currently on the road in support of her album Bangerz, added: "I'm sorry in advance if I am not myself tomorrow Boston. I will try my best to be my best."

Miley's fans were quick to console the singer on Twitter, with the hashtag #RIPFloyd soon trending.

The 21-year old was also left devastated in 2012 after her Yorkshire Terrier Lila unexpectedly passed away, leaving Mi-Cy to tweet at the time: "'For everyone asking... I have never been so hurt in my life.

"My heart has never been so broken..... Lila my sweet baby girl has passed away."

Following Floyd's death, the Wrecking Ball hitmaker is still a mum to dogs Ziggy, Happy and Mary Jane, while also helping out with sister Noah's Yorkie, Penny Lane.
