Amanda Seyfried Looked Ridiculously Hot At The Dear John Premiere (PHOTOS)

Woah, there… where has Amanda Seyfried been hiding that body?? The Big Love actress showed up at the premiere of her new movie, Dear John, at the Grauman’s Chinese Theatre in Hollywood last night and all eyes were on her and her, um, dress. If that doesn’t convince you to see the romance flick this weekend, we dunno what will (well, maybe Channing Tatum, but that’s another story).

Check out all the red carpet pics from last night in our new gallery. What do you think about Amanda’s ultra-revealing Armani dress?
