What makes Rachel McAdams so singular is her ability to be both adorable in a we-want-to-pinch-her-cheeks kind of way, as well as mind-blowingly sexy. Exhibit A: Her impish grin whilst wearing this insanely hot dress.
She literally glows in all of the pictures from last night's premiere of "The Time Traveler's Wife" -- almost as much as Brad Pitt, who coincidentally went with an all-white ensemble (did everyone read our post about August whites?). We applaud both her decision to keep the whole look beauifully simple (note crisp black pumps and wavy, unfussy hair), as well as the amount of double-stick tape probably required to keep that slinky neckline business in place. Nailed it!
