According to Grazia magazine, fashion designer and actress Frost, who is mother to Law's three children, is said to be furious that the couple have reunited and sent him and email to tell him so. According to a source in Grazia, Frost wrote that he would never be happy with Miller. The source revealed, "Sadie said he was mad to go back to Sienna. She said he really changes when he is with her, he becomes stressed and emotionally all over the place." Law is said to have shown the email to his 24 year-old girlfriend, who was incensed enough to write her own reply, saying that she was jealous.
