Khloé Kardashian is ''really proud'' Rob Kardashian.

The 'Keeping Up With The Kardashians' star's brother has appeared to have been growing more alienated from the family but things may be on the mend as the 30-year-old television personality has revealed he is desperately trying to get his ''groove'' back.

She told E! News: ''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.

''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.''

And it's not only sister Khloé that is worried about sock designer Rob, his mother Kris Jenner is also nervous about his emotional stability and has ordered him not to appear on their E! show until he is better.

A source said recently: ''Kris doesn't want Rob on the show when he is emotionally unstable...

''The attitude has always been that when Rob gets his act together, starts working out and loses weight, everything will be good and he will be happy.

''But behind the weight gain is this very unhealthy mental state that he keeps struggling with.''
