While the surprise success of Beverly Hills Chihuahua, which has been No. 1 at the box office for two straight weeks, has thrust the bug-eyed breed into the spotlight, they have a long and storied history as one of Hollywood's favorite breeds. From Bit Bit to Bruiser, PEOPLE.com walks you though Hollywood's Chihuahua Hall of Fame:
Tinkerbell Hilton: The OBHC, or Original Beverly Hills Chihuahua, is the tiniest Hilton who has more accessories than most Park Avenue heiresses, has her own unauthorized biography and was even the subject of a kidnapping scare when she went missing in August 2004. Luckily, the dog was reunited with owner Paris Hilton after a week. "She is like a child to me," Hilton said at the time.
Gidget, the Taco Bell Chihuahua: With her bulging eyes and infectious catch phrase "Yo quiero Taco Bell!" Gidget helped kick off the chihuahua craze with a series of commercials that ran from 1997 to 2000. Befitting her trailblazing status, she had a great later career role as Bruiser's mother in 2002's Legally Blonde 2: Red, White & Blonde, before dying of cancer three years later.
Bit Bit Spears: Few creatures have lived a more charmed life than Britney Spears's canine companion. In her prime, the dog had her own room, complete with pintsized furniture, and was once treated to a $180 steak at Picasso Steak House in Las Vegas. While no longer a constant presence under Britney's arm or on her website, Bit Bit is said to be living out her dotage in the actress' Malibu estate.
Coco Millan: As the smallest member of Cesar Millan's pack on the Dog Whisperer, Coco has spent zero time in haute couture, but it is still managing just fine, thank you. Coco had been brought to Millan to rehabilitate its aggressive behavior and ended up staying when his son, Calvin, fell in love with the dog.
