Ever since Amanda Seyfried and Thomas Sadowski announced that they were engaged in September and expecting their first child together a month later, it seems like they haven't been able to stop smiling. The adorable couple usually keep a pretty low profile, but on Wednesday night they decided to get all dressed up for the glamorous LA premiere of the new film they're in together, The Last Word.
