She tweeted, "Lola you brought love, companionship, and fun into our home for 12 years. You will never be forgotten. Love momma."

Jack has also paid tribute to his favorite pooch, who famously urinated all over the stars' house on their hit MTV reality show "The Osbournes."

He writes, "Lola you were the best friend anyone could ever have. I will love you and miss you always. RIP."

Lola is the second dog the Osbournes have lost in as many months -- Martin died on Christmas Eve.
