Millie Bobby Brown stuns in orange cropped blazer and skirt while promoting her new book in NYC… before rocking cream shorts and white top with fiance Jake Bongiovi

Millie Bobby Brown enjoyed a trendy trip to New York City as she continued her promotional tour for her new book Nineteen Steps, which she wrote with ghostwriter Kathleen McGurl.

Millie, 19, wore a cropped orange button-up top and matching skirt as she arrived at Good Morning America in the Big Apple on Thursday morning.

She was later seen leaving the studios in a different outfit – a cropped white top and beige shorts – with her fiancé Jake Bongiovi.

Her third look was a black and white maxi dress, which she was seen rocking as she left the NBC studios.

Her last look came hours later, when she arrived at JFK Airport with Jake and her little sister.

Millie wore a casual look and glasses during her flight out of the city.

Millie showed off her slim figure in the bright orange long-sleeved button-down top, teamed with matching bottoms.

The skirt featured a criss-cross design, revealing a flash of her flat midriff.

The British actress added velvet blue-gray platform heels, with a matching snakeskin textured clutch.

The teen star pulled her brunette locks back into a tight ponytail and showed off her gold earrings.

She was on her way to the studios for Good Morning America.

Millie was spotted leaving the GMA studios in a different outfit — and with fiancé Jake Bongiovi, Jon Bon Jovi’s 21-year-old son.

The Stranger Things star wore a pair of cream shorts with multiple keyholes along her waist, into which she wove her gold chain belt.

She added a long-sleeved cropped blouse with a gold accent in the center.

The Netflix star, who showed off her midriff in the eye-catching look, wore cream platform heels with large frame sunglasses.

Meanwhile, he cut model fiance Jake a casual figure in a graphic brown shirt, trucker cap, ripped jeans and sneakers as he escorted her back to their waiting car.

Her third outfit was for her appearance on the Today Show; she was spotted leaving NBC Studios in a long-sleeved tie-dye dress, with shades of black and white.

She paired the turtleneck maxi dress with futuristic white heels and the same snakeskin wallet.

Jake was there when they walked out together.

Hours later, the lovebirds were spotted heading to their terminal at JFK Airport with her little sister.

Jake and Millie got engaged in April 2023 after dating for three years.
