Waitress star Keri Russell stopped by Michelle Williams' Brooklyn home this afternoon. Michelle's mom, as well as her best friend, actress Busy Philipps, who also happens to be Heath's daughter Matilda's godmother, were inside. "It was very sweet," an eyewitness tells In Touch. "Keri walked up and handed a card to a police officer. She asked him to give it to Michelle's mom before walking away silently," the insider adds.
