Miley Cyrus has a new reason to smile, and his name is Happy.
The singer brought home a new puppy on Tuesday, adding to her full house of dogs, including Lila, Floyd and Ziggy.
“He was left in a box in front of Walmart,” she Tweeted Wednesday. “I don’t understand how people can be so cruel. That’s why we named him Happy.”
The dog, a possible Rottweiler-beagle mix, has gone “from cardboard” to Maison Martin Margiela, according to Cyrus, who shared a photo of her new puppy lying on luxurious-looking leather.
