Khole Kardashian is opening about her young brother Rob Kardashian on the red carpet while promoting the Kardashian Beauty hair care line on Thursday.

Huffington Post reported that Khole explained to E!'s Maria Menounos that Rob is doing better but she hopes that he can continue to do better and be happy forever.

"Rob definitely has his ups and downs, and he's been struggling for the past year and a half, maybe two years, which I think we've all had those times in our life," explained Kardashian.

Rob is still living with Khole and the two have been working out together and she explained that she wants to be a positive support and motivator for her brother. The public downward spiral for Rob started when he posted a picture on Instagram and he related his sister Kim Kardashian to the main character in Gone Girl. Khole said that she understands that Rob has been dealing with a lot for a long time and isn't going anywhere but to keep supporting him.

"It's not just one thing. I think it's a ton of things. The loss of my father, he's never really dealt with -- he went straight into college after that happened and kind of pushed everything aside and manifested himself in college and did so well and succeeded in school ... Also, losing Lamar in his life was a big thing for him because he lost his next father-slash-brother figure," said The Keeping Up With The Kardashians star.

Radar Online added Rob's personal struggles have been going on for at least two years.
