It’s no secret that Khloé Kardashian has had one of the toughest years of her life.
“What Khloé is going through is definitely challenging, I m not going to lie,” her mom, Kris Jenner, told PEOPLE at her #cirocthenewyear pledge party at L.A.’s Mixology 101 on Tuesday.
“It s also a very interesting time for her because it s very cleansing,” she continued. “She s also showed this side of her that I didn t know she had. I always knew Khloé was strong, but I never dreamed that she had this kind of strength.”
Despite the difficult time, Jenner says her daughter is determined to learn from the experience.
“It s definitely life lessons that she will be able to apply and use later in her life,” she said. “She s learned a lot from this situation.”
The couple were married for four years and Odom became a member of the close-knit clan, so it’s no surprise that Jenner still thinks highly of the NBA star.
“I still love Lamar and I love Khloé, and I hate, hate they re going through this. But if it s something that Khloé feels she needs to do, then I m 150 percent behind her. We all lean on each other, we have to.”
