It was not a Merry Christmas in the Osbourne home yesterday -- their beloved chihuahua Martin died. 

Kelly Osbourne passed on the sad news via Twitter yesterday, writing, "today is a sad day in the Osbourne family house hold we lost R dog martin of 14 years. Devastated does not quite sum it up! #NotSoMerryXmas"

On Sharon's website, Martin is described as "a sophisticated little creature. Shunning the affection of women, Martin prefers the love of a good man."
