Samantha Ronson is beyond sorry.
Ronson's unusually solemn tweet was in reference to earlier today, when her pet bulldog, Cadillac, reportedly attacked a neighbor's Maltese. The smaller pup is said to have died from its injuries.
"I feel incredibly sad and wish I could offer more than condolences, unfortunately there are no words to describe how sorry I am," Ronson continued.
The incident occurred near the celebrity DJ's West Hollywood apartment building.
Someone called 911 at 11:10 a.m. to report that a woman and a small dog had been attacked by a "pit bull." The attack dog was later identified as a bulldog and its given home address matched Ronson's.
Animal Control did visit the scene but left without Cadillac.
Samantha Ronson's dog is one of many Very Important Pets in Hollywood.
