Kendall Jenner shows off her slender frame in a fitted brown onesie as she leaves a gym in Los Angeles

Kendall Jenner slipped into a clinging brown shorts onesie for a workout in Los Angeles on Saturday.

The 28-year-old supermodel — who stars in a new Jacquemus holiday campaign — showed off her svelte physique in the snug look.

The 818 Tequila founder wore a pair of dark shades over her eyes and wore her lustrous locks loose and in a center part.

She carried a cream-colored Cupshe sweater while exiting a Brentwood gym after working up a sweat.

The reality television personality carried a large brown leather tote over her arm while making her way to her car.

She recorded herself standing in front of a bathroom mirror, dressed in pale green-toned biker shorts, a matching bra, and a long-sleeved white shirt worn over it.

The beauty, who is dating Puerto Rican music artist Bad Bunny, clutched her phone with a dark manicured hand.

Kendall, who is the only one of her five siblings without children, recently celebrated her birthday.

She was treated to a slew of heartwarming messages online from her famous family and friends.

On her special day, November 3, big sister Kim Kardashian, 43, uploaded a carousel of pH๏τos with the runway regular.

Kardashian captioned the post, ‘Happy Birthday my beautiful Horse Girl KJ! our road trips and our travels will always be my favorite memories together and I can’t wait to create even more! You always bring the grounding energy we all need. You are such a light! I pray this year will bring you peace and more love and happiness.’
