‘I love exercising in lingerie’ Hailey Baldwin's sexy underwear workout gets pulses racing

Hailey Baldwin is one of the most sought-after models in the fashion industry.

And we’ve all gawped at her incredible figure as she’s been splashed across glossy magazines including Elle and Vogue.

So in the spirit of Christmas, the 21-year-old has revealed her secret fitness tip.

Hailey stripped down to her lingerie for LOVE Advent Calendar’s iconic festive countdown.

Every day in the lead up to Christmas, the brand has been releasing videos of the hottest names in fashion in a series of raunchy scenes.

Today, bombshell Baldwin took centre stage with a saucy workout scene.

Dressed only in Agent Provocateur underwear and lace suspenders, she showed off her enviable figure.

The model flaunted her toned tum and bum as she completed different moves, including squatting and balancing.

While this may seem a bizarre choice of attire for working up a sweat, Hailey seems to enjoy exercising with little-to-nothing on.

In the short clip, which was directed by Phil Poynter, she exclaims: “I love exercising in lingerie... I mean who doesn’t?”

While there’s no proof that working out in your undies improves your fitness, we doubt there’ll be much objection to the saucy video.

Many have commented that this year’s shoots have been the best yet.

In the first week, Rita Ora carried out a sexy dance in a skimpy cut-out leotard. And supermodel Barbara Palvin got eyes-popping with a sensual pole dance.
