She shot to fame as one of the stars of hit reality show The Osbournes.
But Jack Osbourne has revealed his adorable Bulldog Princess Lola has passed away at the age of 12.
The cute dog became a star on the show because of her tendency to do the toilet in the most unusual of places in the family home.
Devastated Jack announced the sad news on Twitter to his legion of fans.
He said: 'Lola you were the best friend anyone could ever have.
'I will love you and miss you always. RIP Princess Lola.'
He later added: 'Thank you all for the kind words about Princess Lola. It was nice she was loved by so many people.'
The infamous animal even had its own account on the social networking site, which was also updated for her 9,000 followers.
It read: 'Thank you all for your kind words. I'm in a better place now.
'Heaven needs a new princess.'
Jack, 26, will no doubt be mourning the passing with the other members of the clan today.
Even Black Sabbath legend Ozzy, who was frequently cleaning up dirt on the show, will surely be down in the dumps.
His son lavished the dog with love and presents, and would even post videos of their antics on YouTube.
One popular example was his hilarious entry titled Lola Osbourne's 2010: A Bacon Odyssey.
It showed him feeding the cute pooch some rashers, which she gulped down with relish.
