This January, always a bridesmaid, never a bride.

Katherine Heigl (Knocked Up, TV's Grey's Anatomy) lights up the screen in this charming romantic comedy from the screenwriter of The Devil Wears Prada. Heigl stars as Jane, a romantic, completely selfless woman who's been a happy, helpful bridesmaid no less than 27 times. But her own fairytale wedding seems to be nowhere in sight, until younger sister Tess (Malin Akerman) captures the heart of Jane's boss (Edward Burns) -- with whom she's secretly in love -- inspiring Jane to change her "always a bridesmaid" destiny.
