Undercover mother! Hilaria Baldwin goes incognito in silver padded hoodie vest and skintight leggings while working out in NY
She was up late with her husband Alec Baldwin at the Clio Advertising Awards in New York City on Wednesday night.
But that didn't stop Hilaria Baldwin going out jogging in Manhattan's West Village neighbourhood of New York on Thursday.
And it looked like the 31-year-old was trying to go incognito for her exercise session.

Who's that girl?: Hilaria Baldwin was almost unrecognisable when she went out jogging on Thursday morning in Manhattan's West Village after spending Wednesday evening with husband Alec Baldwin at the Clio Awards
The yoga expert hid her brunette tresses under the tightly done up hood of her silver, sleeveless padded vest, which was zipped up to her chin.
Hilaria wore it over a grey T-shirt plus skin-tight black leggings. And she pulled on a pair of black and white Nike running sneakers.
The mother-of-two hid her eyes and a large portion of her face behind an over-sized pair of dark glasses as she powered along.

Hilaria is in perfect shape after giving birth to baby Rafael in June, her second child with Alec, 57.
They also share two-year-old daughter Carmen.
Meanwhile Hilaria swung by her publisher, Rodalebooks, to teach yoga to a packed class of employees in a hall.

Class act: Hilaria is writing a lifestyle book, due to be published by Rodalebooks in January 2017, so she called into the office to host a yoga class, which she shared on Instagram
She captioned it: 'Of course my publishers do yoga. Meet my book buddies for #HilariaWritesABook ! Loved teaching today @rodalebooks ... So happy to be part of the #rodalefamily !'
The Spanish beauty took to social media to announce she was writing her first book, about lifestyle, in May.
But fans will have a long wait. It isn't due out until January 2017.
