For the first time since her Maltipoo Daisy was taken from her, Jessica Simpson speaks publicly about the loss of her pet.

"Daisy meant the world to me," the star, 29, told Usmagazine.com at the FFANY Shoes on Sale QVC event in NYC Tuesday. "I hold her memory very, very close. It was an unfortunate thing what happened. That I don't have her every day... It's a very hard thing to talk about."

Daisy, the five-year-old dog who was a gift from ex-husband Nick Lachey, was dragged away by a coyote in her Los Angeles backyard in September. After a week of searching -- which included hanging posters that offered a reward and enlisting professional pet finders FindToto.com -- Daisy was never recovered.

Simpson still is unsure if she will get a new dog."I haven't really thought about another dog yet, but maybe sometime," she told Us. "[Daisy] would want that."

On Sunday, the star Twittered that she didn't appreciate pranksters sharing false information about Daisy with her loved ones. "People who have been contacting my family and friends saying that Daisy has been found," she posted. "Untrue. People are so cruel... please respect her memory."
