Hell hath no fury like a woman songwriter scorned! Mandy Moore is hitting back at "toxic" ex-boyfriend Zach Braff in her song, "Looking Forward to Looking Back," on her new Wild Hope album, says the New York Post. "There are references to his Hollywood Hills home in the song," says a music insider. "We all assume it was about Zach, he was such a cheater." Mandy herself has said, "The whole record is very personal. I wanted to be as honest as possible." The truth hurts sometimes, huh, Zach?
