The 33-year-old model – who has previously been in relationships with cage fighter Alex Reid and Australian singer Peter Andre - insisted she isn't doing the show as an attempt at being 'famous or massive' in America.
She told The Sun newspaper: 'It's taken nearly a year to set this contract up. We're thinking of doing the road trip from New York to Los Angeles.
'But I want a big Priscilla-style van. You've got to make it fun. The cameras will be inside the van. That's what we're working on at the moment.
'I'll be in America in September and they're trying to work out what they want to do. I'm not trying to be famous or massive, I'm just doing what I want to do.'
Katie – who has previously appeared on documentaries Jordan: Living With a Dream and Jordan & Peter: Laid Bare - also revealed she is planning on having a road trip theme for her next UK reality TV programme.
She explained: 'Even over here the next reality show I'm doing is going to be a road trip to make it more interesting.
'I don't think anyone wants to see me in the hairdressers and getting my nails done all the time.'
Looking forward to this. I fell in love with her when I first saw her half assed E! reality show years back. She is hilarious and doesn't give a shit what people think about her.
