TMZ reports that Hilton first purchased Tinkerbell in 2002 from an online breeding company after being inspired to get a pup from the film "Legally Blonde."

Tinkerbell later appeared on Hilton's reality show "The Simple Life," where she starred alongside Nicole Richie.

Later in 2004, Tinkebell was abducted by burglars who invaded Hilton's home. At the time of the abduction, Hilton offered a $5,000 reward but, six days later, Tinkerbell reappeared and Hilton never offered an explanation for how her canine companion resurfaced.

The death of Tinkerbell follows Hilton's recent appearance at Coachella with her sister, Nicky Hilton.

The two sisters celebrated Coachella in white outfits in honor of National Siblings Day.
