That Heidi Montag went from a pair of (very nice) barely-there boobs to DDD's speaks volumes.
From College Candy: "Heidi is now famous for being married to Spencer Pratt and looking like a Wax Museum copy of herself. It’s actually kind of sad. No one probably remembers this, but she was really cute at the beginning of [The Hills]! Heidi looked like an all-America surfer chick, someone any guy would be happy to bring home to mom. Then she became 'addicted' to plastic surgery and it all went down hill (or to a size DDD) from there."
