Pop superstar Lady Gaga has revealed that she has been deeply saddened by the death of the dog her family had since she was a child. 

Writing on her official Twitter page this morning (October 30), the 'Applause' sensation explained that she regrets not "being there" for the pet, who had been battling cancer, and she can't believe the loss:

"My puppy Alice died. We had to put her down, cancer ate away at a little angel. My daddy is so sad, we all are, lost a member of our family. I love being an entertainer but it is so painful sometimes to be away from home 17 years she held on, so many memories. Nothing beats family."

Gaga added: "I remember her laying my bed, she knew when I was sad, or when I was sick. I should have been there. I just pray Alice found her wonderland."

Her father, Joe Germanotta, also shared a snapshot of the pooch and accompanied it with the touching caption: "Good nite Alice, you were the greatest."
