Stephenie Meyer looks amazing!

On Tuesday, the "Twilight" novelist showed off her massive weight loss at the premiere of "The Host" in Hollywood.

Wearing a floral belted vintage style dress, a black sweater and her hair in side-swept curls, the writer looked almost unrecognizable from her former self at the "Twilight Saga: Eclipse" premiere three years ago!

Looks like the 39-year-old is on top of the world right now -- "The Host" is Meyer's latest film adaptation of her widely popular novels.
