Hailey, who is the daughter of actor Stephen Baldwin, looked pretty in fitted blue jeans, a summer white shirt and a black cap. The Topshop jeans model was also strapped into a half-leg cast on her left foot, after spraining it in a recent accident.

Joining her in the gorgeous stakes, Kendall stepped out in white cropped skinny jeans, a black, Lynyrd Skynyrd crop top, beige boots, and aviators.

Meanwhile, Justin kept on his work-out sweats and a headband, which he wore to play a game of basketball at the gym.

The seemingly inseparable friends’ gym date comes a day after Hailey and Kendall were spotted supporting Justin at his comeback show at KIIS FM’s Wango Tango in Carson, California, on Saturday.

The 21-year-old superstar returned to the big stage for his first solo performance following a two-year hiatus, to headline the day-long concert with Kanye West. Kris, her beau Cory Gamble, and mutual pals, including Jaden Smith, were also in attendance.

After thrilling the Wango Tango audience, it looks like the close-knit group decided to chill out after their next-day gym session and catch some rays.

Back in Calabasas, Kendall Instagrammed a shared bikini selfie with Hailey showing the models lounging on an inflatable swan in a swimming pool.

Finishing the day off at church :)”

Justin posted his own tribute to his mom, Pattie Mallette. The “Where Are U Now” singer shared a photo of Pattie wearing flight headgear with a heartfelt message.

Part of his lengthy note read, “If it wasn’t for this woman lets just say I would have had a way LONGER stupid phase. I love u and thank u for not giving up on me!”
