Reality TV star Khloe Kardashian is "really proud" of her younger brother Rob's progress during last week.

The 30-year-old's brother appeared to be growing more alienated from the family, but things may be on the mend as Khloe says he is desperately trying to get his "groove" back, reports eonline.com.

`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,` the `Keeping Up with the Kardashians` star said.

"For the last week, he's been doing better, but I want Rob to do consistently forever. So right now, I'm really proud of him. He's been working out a little and trying to get his groove back. And he acknowledges it! He's aware that he's very introverted and of course not the way he used to be. I think being aware is probably the best thing,` she added.
