At Us Weekly's 25 Most Stylish New Yorkers bash Sept. 15, Stewart, 68, scolded Simpson, 29, calling the incident was "pretty sad." She said Simpson "should have been more careful" and also advised the singer to "get another dog."
"I said that she should have been watching her dog more closely, but I feel very, very sorry for anybody that loses a pet," she said Thursday. "Jessica, I hope you find your pet, but if you don't, I'm really sorry that you lost one."
