Kendall Jenner showcases her abs in Nike set as bestie Hailey Bieber flashes her legs in LA

The models have been friends for years, prior to their successful careers.

And on Friday, Kendall Jenner and Hailey Bieber made sure to make time for their friendship as they enjoyed a fun day together in West Hollywood.

Kendall, 25, flashed her abs in a Nike ensemble as Hailey, 23, showcased her toned legs in an oversized sweater and shorts for a smoothie run following their workout session.

Kendall, who turned 25 on Tuesday, put her flat and toned midsection on full display in a Nike sports bra and matching leggings.

The statuesque brunette beauty added a cropped black jacket as well her coordinating Nike sneakers.

Kendall rocked a dark green mask with her matching sunglasses, opting to leave her brunette tresses center parted and loose around her.

She opted to go makeup free for her Friday outing, which consisted of a joint workout session with Hailey followed by a smoothie run.

Kendall was seen holding on to a purple hued smoothie, as well as a bag.

Meanwhile, equally gorgeous Hailey gave some love to her husband Justin Bieber by rocking an oversized sweater that said ‘Bieber’

The leggy blonde showcased her toned stems in tiny black spandex shorts, adding white socks and sneakers.

Hailey also wore a black mask with her tresses loose around her, also going makeup free. 

The pals were joined by another friend – equally stylish; the mystery friend donned leggings with a top she tied up, highlighted her midsection.

Their outing comes just one day after the latest Keeping Up With The Kardashian aired, which focused on Kendall and Kylie after their epic fight in the car.

The duo did not speak to one another for ‘about a month’ after their physical brawl in Palm Springs.

Kendall and little sister Kylie, 23, had a physical fight in a car during a family trip to Palm Springs.

Kendall asked if Kylie is she could drop her off at home in Bevelry Hills in their car but she said no, with the night ending  with the sisters hitting each other.

A month and a half later, the sisters still hadn’t spoken to each other, despite their family begging them to do so.

Mom Kris Jenner begged Kylie to talk to Kendall but she ignored her.

Kendall was reading a book called Only Love is Real, which bore a passage on pride being an extension of fear. 

‘It just reminded me of my sister. Because we both are alpha and tough girls,’ Kendall said. 

She reached out to Kylie, who finally called her back, apologetic.

‘I just wanna say that the other night got completely out of control,’ Kylie offered, saying she hadn’t known Kendall wanted a ride home.

‘I think it was just miscommunication, and obviously I would never do anything to hurt you. It just shouldn’t have ever gotten to that point.’

Kendall agreed that neither of them had been acting rationally.

‘I’m just ready for it to be over,’ she said in a confessional. ‘Sisters are sisters. We can fight all we want and say crazy things to each other, but at the end of the day we’re a family and we love each other so much. She’s my partner-in-crime, always has been my entire life, and that will never change. So her not being in my life for a month-and-a-half was not ideal.’

‘I love my sister, and there’s no need to ever not talk for that long,’ Kylie agreed.

In a preview of next week’s episode, the Kardashians agreed that Khloé and Tristan had recently slept together, and Tristan told Khloé, ‘I want you in my life.’

Keeping Up With The Kardashians will return next week on the E! network.
