Paris Hilton went "ballistic" when a shop worker refused to sell her a puppy. The hotel heiress was on her way to a photo shoot when she called in at The Puppy Store on Los Angeles' Melrose Avenue and tried to buy a Yorkshire Terrier.

A source told the New York Post newspaper: "Paris wanted a puppy in the picture with her so it would look cuter. She tried to buy a Yorkie but the employee refused to sell it to her, saying it was clearly an impulse buy. "Paris went ballistic and started screaming, 'I love my puppies! I want my baby!' However, they still wouldn't sell her the animal." The store had no comment on the incident. This is not the first time Paris' animals have got her into trouble.

In 2005, she angered California's animal authorities when she bought a kinkajou during a trip to Las Vegas. The 26-year-old star was eventually forced to give up the racoon-like pet, which she named Baby Luv, after it was deemed to be illegal to own as a pet. The same year, Paris was also allegedly forced to return a baby kangaroo after having it flown to the US from Queensland, Australia.
