Star of Keeping Up with the Kardashians Khloé Kardashian is backing up her brother, Rob Kardashian in his custody battle with his ex, Blac Chyna. It's reported that Rob is looking to gain primary custody of his daughter, Dream Kardashian.

Rob was last in the news for his ongoing and toxic relationship with Blac Chyna when the two dated back in 2016. The couple ended up having a daughter, Dream Renee Kardashian. The two eventually split for good in February 2017. Kardashian also posted sexually explicit pictures of his ex-girlfriend on social media, which led Chyna gaining a restraining order against him. It's been a very stressful relationship for Rob and the rest of the Kardashian family.

According to reports by TMZ made on January 7th, Rob alleged that his ex, Chyna, is constantly hosting parties at her home while their 3-year-old daughter is present in a sealed court filing they obtained. He also alleged that Chyna is abusing illegal drugs, claiming she "snorts cocaine," and has a drinking problem, sometimes spending "$600 on alcohol" daily. Khloé then made a statement in the report claiming that Dream has become "decidedly more aggressive" lately and she doesn't want to go home to her mom. Rob also has alleged that Chyna has an anger problem that has resulted in violent acts, claiming she threw "sharp objects" at her hairdresser. Rob is seeking to have Chyna's parenting time reduced to having Dream just weekends with a nanny present at all times.

Rob is looking to better his life as he's been losing weight and working toward a healthier lifestyle to better his life. Now, he's seeking to better his daughter's life by asking for primary custody of his 3-year-old daughter. It's reported by People that Rob's sister, Khloé, is ready to support her brother and her niece at all costs. A source close to the famous family told the magazine, "Khloé has always been very close with Dream." The insider revealed, "When Rob had custody of her as a baby, Khloé often helped out. She really loves Dream." In fact, Khloé is so passionate about doing what's "best for Dream" and Rob that she "will do everything she can to help Rob get custody." 

As fans know, Khloé is close to all of her many nieces. However, since she has her own daughter, 20-month-old True Thompson, whom she shares with ex Tristian Thompson, she's even more protective than before of Dream. Khloé is also very close to Rob, as even at one point on Keeping Up with the Kardashians fans remember Rob lived with her and her then-husband Lamar Odom for a time.
