Kendall Jenner shows off her tiny waist in a pair of skintight black leggings while heading for workout session with her BFF Hailey Bieber in LA

Kendall Jenner and her longtime best friend Hailey Bieber bundled up on a chilly day as they headed to a workout session together in Los Angeles over the weekend. 

While sporting a bulky black leather jacket and brown leggings, the 24-year-old wife of Justin Bieber rocked a high ponytail and toted a warm beverage.  

Jenner showcased her tiny waist and long legs in a pair of skintight black leggings, which hugged every curve of her incredibly toned frame. 

 

While Hailey was on her gym-ready ensemble with her $500,000 engagement ring, furry white slippers and matching socks.
