Kendall Jenner and her best friend Hailey Bieber are seen leaving a hot pilates class in LA

Kendall Jenner and her best friend Hailey Bieber are back working out after enjoying a wild weekend in Aspen to celebrate 2023.

The Vogue models were seen with damp hair and activewear as they left a pilates class at Get Hot inside Sunset Plaza in Los Angeles on Tuesday. Classes are $40 each.

They walked one after the other to their cars in the parking lot, unable to crack a smile in the rainy afternoon.

Kendall wore a navy bra with matching high waisted leggings while adding a chocolate brown leather jacket that was worn open.

The cover girl also rocked white sneakers with matching socks.

And Devin Booker’s ex pulled her wet hair up into a messy bun while adding sunglasses and a face mask.

The Keeping Up With The Kardashians veteran appeared distracted as she focused on her cell phone as she walked to her vehicle.

Also in his hands was a large cherry red water bottle.

Hailey looked like she just stepped out of the Matrix as she had on an oversized black leather coat with a heavy collar and belt.

Underneath, Justin Bieber’s wife wore black sportswear and added black slippers.

The star wore her dark brown hair down and added some very thin sunglasses while her hands were busy with a cell phone, a bottle of water and a thermos.

Interestingly, she was wearing Justin’s huge diamond engagement ring, which looks like a very expensive piece of jewelry to wear to a training session.

This comes after Kendall went out partying with Hailey, her husband Justin and her sister Kylie Jenner in Aspen.

Also there was Kylie’s daughter, Stormi, and her best friend, Stassie Baby.

Kendall and Hailey were spotted not only going out to dinner with the group, but also out on the slopes. They were seen flying back to Los Angeles on Monday.

Kendall appears to be single.

In late November it was claimed that she had not had a “horrible breakup” with Devin Booker.

The 27-year-old model had been in an on-and-off relationship with NBA player Devin, 26, since 2021 and while the couple are said to have ‘quietly’ split for a second time in October, a source close to the star The Kardashians have alleged that their breakup was simply the result of scheduling issues.

The source told E! News: ‘Their schedules didn’t align and eventually the relationship really ran its course. There is no bad blood. It wasn’t a terrible break up.

The insider went on to say that 818 Tequila founder Kendall has been in “good spirits” since resigning from Devin and is focusing on taking her company to the “next level” so she isn’t interested in finding someone new.

The source added: ‘Kendall has been in a great mood since the split. She has been very busy and is trying to take her company to the next level, and she is really focused on work. She’s not really open to dating right now.

However, the comments come just days after it was alleged that Kendall and Devin still plan to keep in touch despite calling it quits.

A source said: “They have a lot of love and respect for each other and only want the best.”

The apparent split comes months after Kendall and Devon first split, with Page Six reporting in June that they were on “different pages” about their relationship.

A source told the outlet: “While they look out for each other, Devin wasn’t going to propose and his priority is his career.” Kendall’s career also dominates her life.’

Not long after news broke that they had ended their two-year relationship, the couple were photographed together at Soho House in Malibu. A source dismissed it as a “PR stunt” and added: “(Kendall’s) team doesn’t want it to look like she was dumped.” Her people requested the meeting. They were most recently seen vacationing together in Hawaii in August.
