We learned late last night that Miley Cyrus' beloved dog, Floyd, passed away suddenly.

Miley went to Facebook to break the news:


She is performing in Boston today, and offered up this message to her fans, hoping that they don't take it too hard if she isn't herself on stage:

Keep in mind that she already missed Boston's Jingle Ball back in December due to a bad snow storm, so it should be interesting to see what happens out there for the concert tonight.

I feel so bad for her. Wishing her the best during this difficult time.
