Kendall Jenner and Hailey Baldwin present their legs in a tiny shorts while they head for Pilates

They are the best friends of the most wanted models in the world.

And Kendall Jenner and Hailey Baldwin proved to be worthy of both titles since they were spotted defect-free in Los Angeles on Saturday.

The 23-year-old reality star cradled tiny black shorts and a gray hoodie while Justin Bieber's 22-year-old wife followed Kendall's example in pink and white hooded shorts.

Dazzling, the Kardashians star flaunted her pretty pins while her shorts were high on her thighs.

Her raven braids were tied in a loose bun allowing her to see her natural beauty.

Stephen Baldwin's daughter has also made his blonde signature.

The beautiful friends were then seen at the exit of PIlates studio and seemed animated after the hard workout.

Hailey peeked at her muscular belly as she swayed a pink halter.

This comes after Hailey had a party with Kendall, Elsa Hosk and Cara Delevingne while Justin stayed home to deal with a feeling of "super offline and weird". last month.

Kendall opted for a short-printed python top that dipped to his belly button and a ruffled skirt on Ronny Kobo's hip. She continued her eyes with elegant hair and brown strappy stilettos.

Meanwhile, Hailey seemed glittering in a studded mini-dress that squared off her cleavage.

On Tuesday, Bieber shared some pretty videos of himself traveling with his wife.

The sweetest moment came when Hailey jumped to give Justin multiple kisses on the cheek and then on the lips.

The social media release comes a few days after he talked about some of his personal difficulties in a candid new Instagram.

"I fought a lot," admitted the Canadian pop star. – I just feel super offline and weird … & # 39;

But now, Justin has started a new chapter in his life, having married his long-time friend and loving lover, Hailey, last year.

It seems that Justin is currently seeking treatment for his depression and, although he is personally fighting, his wife is not at the root of his problems. "It has nothing to do with Hailey. He is very happy to be married to her. It's just something else with which he struggles mentally, "said a source to People. "He has a good helper around him and is cared for. He seems confident that he will feel better soon.

Hailey also supported her treatment: "She has supported him so much throughout this process," said a source at Us Weekly.

The couple would have suspended his religious wedding plans while he was focusing on his mental health. Last month, a source told People magazine: "They will eventually organize a wedding ceremony with their family and friends. However, for the moment, Justin's attention is recovering mentally.

And Kendall seems really happy for the two lovebirds as she was asked about their engagement for The Tonight Show with Jimmy Fallon in September.

& # 39; Are you happy [Hailey] and Justin Bieber are engaged? I think it's perfect. They are so in love, asked Jimmy.

Kendall replied, "Yes, no matter what makes them happy, I'm happy. I have been friends with them for a very long time. So everyone is happy and that makes me happy. & # 39;

Later in the day, Hailey presented his sporty ensemble for a chic and cool rocker vibe.

She donned a black top and a black motorcycle jacket on her hips while framing her juvenile face in a set of purple-tinted glbades.

And she roamed the streets with clbadic Converse white tops while pulling up the pants from her jeans.
