For the past few years, Khloe Kardashian has been through a lot, such as struggles with her body weight, and a tumultuous relationship with her ex-husband Lamar Odom.

Eventually Khloe began working on her fitness and divorced Odom - which was temperately put on hold after he had a drug overdose at a Las Vegas brothel.

Now, the reality star has found happiness with her basketball playing boyfriend, Tristan Thompson, and is expecting her first child in March.

While she's moved on with her life, and has furthered her brand (with TV show Revenge Body with Khloe Kardashian, and other business ventures), there are some people who are still living in the past.

Namely Khloe's aforementioned ex-husband, who is still talking about her in interviews.

Following their divorce in 2016, Odom's life hasn't amounted to much. The father-of-two appears to have relapsed after vowing to stay clean, and hasn't played professional basketball since 2013.

Now, in an interview with BET's new show Mancave, Odom is back in the spotlight, and didn't waste any time insulting his ex when he discussed how he knew their relationship was over.

"I understand when it's over, it's over," Lamar said. "When she was with her second or third NBA ball player, I can see that."

After Khloe's big sister Kim Kardashian caught wind of Odom's jab, she wasted no time to her defense.

"Or second or third brothel," Kim wrote on Twitter, referencing Odom's frequent visits there.

Everyone seemed to appreciate Kim's snarky tweet, including close friend and mode Chrissy Teigan were impressed by her response.

It's pretty great to see Kim show support for her sister, and hopefully Khloe won't take Odom's words to heart as she prepares for her little bundle of joy.

What do you think about Odom's comments?
