Willis, 23, announced her new dog's arrival on Twitter last weekend. "So happy she and her bro Happy can play together," she wrote.
While Willis initially settled on the name Dita Blue for the pup, she later decided it didn't fit, so she took to Twitter to ask fans for suggestions.
The puppy joins the actress's four other dogs. Of her expanding brood of pooches, Willis wrote, "We are crazy but I love it."
