The 28-year-old star has landed the role of co-host on 'The X Factor' USA alongside Mario Lopez and has turned to the 'American Idol' presenter - who produces her family's reality TV shows - for advice on her new job.
A source told HollywoodLife.com: ''Khloe has been leaning on Ryan for hosting tips. Ryan has been advising her to not speak too fast while on camera because when people get nervous they tend to speed up their speech. He is also reminding Khloe not to take things too seriously and to always have fun.''
While Khloe is nervous about her job on 'The X Factor' - which is the brainchild of Simon Cowell - she is doing her best to ensure she is well-prepared for when the live stages of the contest start.
The source added: ''Khloe is nervous, but also very excited. She's nervous because it's live TV and that is not something she is used to.
''She has been doing her homework, watching 'The Voice', basically any show that has a host. She wants to be as natural as possible and not let her nerves get the best of her. She is getting lots of support.''
