Paris Hilton

The ‘Paris In Love’ star was rarely seen without a cute critter during the 2000s, with her most famous pet being her beloved chihuahua Tinkerbell.

Paris built a $325,000 two-story doghouse replica of her own mansion in her garden that boasted plush furnishings and air conditioning.

In 2009, the 42-year-old socialite said: "They love to run up and down the stairs and chill on their balcony.”
