Khloé Kardashian is slowly warming up to the idea that brother Rob is in a relationship with Blac Chyna. The “Keeping Up With the Kardashians” star is said to have initially struggled with the news but now wants to support her brother.

A source close to the family told People magazine it was hard for Khloé, 31, to accept that Chyna played a big part in helping Rob get back on his feet because Khloé herself had gone above and beyond to be there for him in his time of need.

During Rob’s retreat from the spotlight because of a reported 100-pound weight gain and battle with depression, he was living with his older sister. “Khloé loves and supports Rob, and always has. She’s always been his biggest supporter and has been trying to get him on the right track for years,” the source told the outlet. “So, naturally, it was a little harder for her to accept the fact that all of a sudden Blac Chyna was the one who got him into the land of the living again.”

The source went on to say that Khloé “didn’t understand” why Rob wasn’t taking help from his family and felt the sock designer, 29, didn’t “appreciate” them. “Rob and Khloé had some tough times, like he did with the rest of the family,” the source said. “But the bottom line is, he’s her little brother. She’ll never turn her back on him.”

As previously reported, Rob and Khloé had a falling out shortly after he started dating Blac Chyna. During a recent episode of the family’s E! reality show, Khloé said she had kicked Rob out her home after he and Blac Chyna littered her place with trash and alcohol bottles.

However, a source told Us Weekly the siblings made up three weeks ago when Rob told his family that Blac Chyna is pregnant. “They worked things out,” the source said. “The baby brought them together. Rob is having a baby, which is huge, and she needed to be there for him. It was the right thing to do.”

 Last month, Khloé posted a sweet picture to her Snapchat page of her and Rob holding hands. She captioned the photo, “Rooooobbbbb.”
