Hailey Bieber shows off her incredible legs in a black mini-dress in New York City

HAILEY BIEBER is one of my favourite pin-ups – and with legs like these I think you can see why.

The American model, wife of popstar Justin, was pictured in a black mini-dress, leather jacket and matching heels as she headed to meetings in New York.

It wasn’t all work for Hailey however, as she was later seen in Los Angeles partying with her best pal Kendall Jenner at the launch of her 818 tequila brand at The Nice Guy.

The supermodel held a star-studded bash at the swanky celebrity hangout with a number of other big name guests, including her famous sisters Kim Kardashian and Kylie Jenner.

Hailey works hard and plays hard – and admitted she didn’t have to worry about what she ate because she exercises so much.

She explained: Exercise keeps my mind…and my body really healthy.

“I really like Pilates and boxing for cardio.

“And I’ll do a couple of sessions a week in the gym, weight training and cardio.”

I need to take a leaf out of Hailey’s book.
