Arguably one of the most recognizable commercial celebripups, she's best known for a voice that's not her own. The infamous male voiceover of "Yo Quiero Taco Bell" starred none other than the female Gidget, whose huge ears and bright eyes charmed a country in the late '90s, despite the controversial ad campaign itself.
Now, sadly, PeoplePets.com reports that the 15-year-old Chihuahua suffered a stroke on Tuesday night and lives no more. Although Gidget was "mostly retired," she would still accompany her trainer, Sue Chipperton, as recently as a February "Hollywood Animals" shoot for People:

Gidget's happy to sleep for 23 hours and 45 minutes a day. She'll lay outside when it's 105 degrees. I like to joke it's like looking after a plant.

Seems like she lived a happy life right up to the end, just relaxing and hiking but her alert expression always knew where the camera was — rest in peace, little superstar!
