They have known each other since the early 2010s and have been best friends for years. They hang out a lot, do grocery shopping, and even go to work out together.

In April 2021, Kendall Jenner and Hailey Bieber were spotted twinning in activewear while heading to Forma Pilates in Los Angeles.

Kendall wore a scoop-neck sports bra paired with Sculptflex high-rise leggings from Set Active, highlighting her long, slim legs. She added a knit cropped cardigan in the same chocolate brown tone by Danielle Guizio for an extra layer.

Wearing her brunette locks down, the 25-year-old model kept it low-key with $170-Dmy by Dmy “Valentina” tortoiseshell sunglasses and an $8 Skims seamless clay-colored face mask.

She held a Takeya Go Cup steel water bottle in one hand and carried her stuff in a sleek By Far “Kiki” dark brown pochette.

Arriving separately at the studio was her best friend Hailey Bieber, who went for coordinating black sportswear. Showcasing her cleavage and rock-hard abs, Hailey wore a $20 Sorella black ribbed reversible twist bra and high-rise leggings.

The 24-year-old model also sported a knit cardigan to somehow conceal her flesh.

To elevate her casual athleisure, Justin Bieber’s wife accessorized with gold jewelry, including a pair of $1,850 Anita Ko Zoe Braided Huggies earrings, a $140 Fallon Short Herringbone chain necklace, a $5,250 Shay Jewelry Diamond Infinity Y necklace, and an $8,750 Jacquie Aiche diamond Y necklace.

She wore her blonde locks up in a center-parted bun and covered her face with a black facemask and $169 Lu Goldie “Lotte” sunglasses.
