Kim Kardashian is ''so proud'' of her sister Khloe for presenting 'The X Factor'.
The reality TV star was based in Miami for the past few months filming a new season of her reality show 'Kourtney and Kim Take Miami' but Kim tuned in to watch her sister on Fox every week and was impressed with Khloe's skills.
She wrote on her website: ''Being in Miami for the last few months I really missed Khloe! It was so great to be able to turn on the TV every Wednesday and Thursday night to watch her on 'The X Factor'. I'm so proud of her!
''It's like she was born to be a presenter. She did such an amazing job this season.''
Khloe - who is married to Clippers basketball star Lamar Odom - previously revealed that her sister had given her constructive criticism on how to improve her presenting skills.
She explained: ''My sisters have already texted me tips, which I love. I love constructive criticism. I've never done this before, so I just think I can only get better - hopefully.
''My sister Kim was like, 'You did amazing, but don't yell so much!' I did notice at some points, I was like, 'Why did I just yell?'''
