Sad news, today. Martha Stewart’s beloved Himalayan, Mozart, has gone to the Rainbow Bridge:

There’s sad news on the celebrity pet owner front today: Martha Stewart’s 19-year-old cat, Mozart, has died. Stewart took to Twitter this morning to tell her followers of his passing, saying the lynx-Himalayan had “a beautiful life.”

The animal-loving domestic doyenne has had a tough year: She lost her beloved chow Paw Paw in April of 2008, and her chow puppy Ghenghis Khan was killed in a deadly kennel explosion on March 6. Mozart was laid to rest right next to Paw Paw on her Connecticut property, she wrote on Twitter.

Stewart is also mom to French bulldogs Francesca and Sharkey.
