She was reading to a sold-out audience at Carnegie Hall.
And Bella Thorne looked nothing short of showstopping as she marked the special occasion in not one but three incredible outfits.
The actress, 21, was first spotted arriving to the historical landmark wearing a gold tiger print Prabal Gurung suit, before changing it up into two more incredible outfits.
Showing off her chic and wild sides, Bella had heads turning as she stepped outside of her car rocking a pair of circular pair of Chanel sunglasses.
The actress turned the sidewalk into her own personal catwalk as she posed up a storm, hand in hand with her beau.
Opting for a natural and clean look, the star wore her fiery locks down in loose, natural waves along with a slick of lip gloss.
She jazzed up the look with an array of silver jewelry, including a statement choker necklace which read 'NYC Girl'.

Ditching the suit, the actress wore a glittering metallic gown that cascaded towards the floor while showing off ample amounts of skin.
