Kim Kardashian has been giving her younger sister Khloe tips on her ‘X Factor’ performance.

Khloe Kardashian has been getting presenting tips from her sister Kim.

The ‘Keeping Up With The Kardashians’ star has joined Mario Lopez as co-host for the US ‘X Factor’ and while she was nervous about her first live show on Tuesday (30.10.12), constructive criticism from her big sister helped.

Khloe, 28, 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?’

“In the audience everyone’s screaming, so in my head I want to talk so the audience can hear me. But, really, you’re talking into the mic, so the viewers can hear you [and] I don’t need to yell.”

Khloe is thrilled to have her first week behind her and is now planning to watch back over her own performances so she can see where improvements need to be made.

She added: “I’m going to re-watch what I did and learn from it and critique what I did. … Now that I understand everything, I think next week can only get better. “
