Baby's got style! Mom-to-be Chrissy Teigen shows off her bump in three different outfits as she continues to promote best-selling cookbook Cravings

She's been going nonstop since her popular new cookbook Cravings was released last week.

And on Wednesday Chrissy Teigen showed off three outfit changes as she continued to promote the book, which has since become a New York Times Best Seller.

The 30-year-old first showed off her bump in a skintight navy blue dress, before covering it in a flowing black dress and coordinating jacket.

Chrissy was spotted arriving at The Daily Show with Trevor Noah in a loose-fitting black dress, worn underneath a stylish, black jacket.

The heavy winter jacket fell to the model's ankles, and she accessorized the look with a pair of thigh-high, black leather boots.

The mom-to-be hid her growing bump underneath the loose-fitting ensemble, which was paired with a chic, black leather handbag.

Chrissy wore her long, caramel tresses in a side part, and styled in soft waves which cascaded over her shoulders.

Her lips were highlighted with a bright red lipstick, as she hid her eyes behind a pair of Aviator-style sunglasses, and sported dangling, silver earrings.

Chrissy looked to be in good spirits after taping the nighttime talk show, and was spotted smiling as she walked with her hands in her pockets as she left the studio.

Earlier that day Chrissy was spotted wearing a similar outfit as she left her apartment on her way to a taping of Watch What Happens Live.

She was not sporting the coat at the time, revealing more details of the low-cut, loose-fitting black dress.

The flowing number featured a button down front and a thigh-high slit that highlighted Chrissy's toned pins.

The mom-to-be was spotted cradling her growing bump as she walked, and could be seen sporting a lighter, soft pink shade of lipstick.

And instead of showing off soft waves, Chrissy's hair was pulled up into a stylish crown braid for the outing.

And before making her Watch What Happens Live appearance, the cookbook author was spotted in Soho wearing yet another look.
