Lady Gaga toned down her usual colorful clothing on Wednesday when she stepped out in London wearing a head-to-toe all-black ensemble, from her over-the-knee black boots to a massive black hat that covers up her eyes.  The ensemble likely was inspired by the fact that the singer is mourning the death of Alice, her childhood dog.

"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," Gaga tweeted on Tuesday.  "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."

The devastated singer 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."

Gaga then retweeted a photo from a fan captioned #RIPAlice.  The black-and-white photo shows a young girl sitting on the floor with a black puppy nearby.  It's not clear if the photo is actually of Gaga as a little girl.
