She's come a long way since she made her red carpet debut at The Twilight Saga premiere back in 2008.
But Stephenie Mayer proved her Hollywood transformation is complete as she turned out to the world premiere of the final movie adaptation of her hit franchise, The Twilight Saga: Breaking Dawn - Part 2, in Los Angeles on Monday night.
Opting for a look of classic elegance, the author of the vampire romance series dazzled in a dramatic silver and grey fishtail floor-length skirt, which she teamed with an unusual black belted shirt.
Meyer completed her red carpet ensemble with perfect porcelain skin, a slick of pink lipstick and her dark locks falling in tumbling waves around her shoulders.
The writer seemed to be taking the event completely in her stride as she posed for photographs with fans and signed copies of her now-legendary books.
And posing alongside the movie's leading cast members, Taylor Lautner, Kristen Stewart and Robert Pattinson, Meyer could have even passed for one of the Twilight stars.
The literary genius cut a very different figure as she hit the red carpet for the premiere of The Twilight Saga: New Moon in Westwood, California, back in 2009.
Looking somewhat awkward as she posed in front of a startling array of flashbulbs, the brunette didn't seem at all at ease with her new-found fame.
Meyer had once again opted for a fishtail number, but the black and grey dress did nothing for her curvaceous figure with its cut-off arms and tight material stretching across her waist.
In addition to the film adaptations of Twilight, the novels have sold over 100 million copies worldwide and have been translated into 37 different languages.
And Meyer has previously admitted the idea for Bella and Edward's love story came to her in a dream.
She said: 'In my dream, two people were having an intense conversation in a meadow in the woods. One of these people was just your average girl. The other person was fantastically beautiful, sparkly, and a vampire.
'They were discussing the difficulties inherent in the facts that A) they were falling in love with each other while B) the vampire was particularly attracted to the scent of her blood, and was having a difficult time restraining himself from killing her immediately.
'I was so intrigued by the nameless couple's story that I hated the idea of forgetting it; it was the kind of dream that makes you want to call your friend and bore her with a detailed description.
'I didn't want to lose the dream, so I typed out as much as I could remember, calling the characters "he" and "she." From that point on, not one day passed that I did not write something.'
