Putting on fake Albuquerque accents, Kendall strapped on a fake pregnant belly and hid under a frizzy red wig while Kylie was a little easier to identify in glasses and a long dark wig with bangs.

When the tour bus driver pointed out Chin Chin – supposedly their sister Kim's favourite place to eat in LA, Khloe screeched: 'Kardashians? The Kar-trash-ians? I don't want to talk about those Kartrashians.'

While sightseeing with mother Kris in Rome, Kendall became upset after a paparazzi cut their trip short.

Kris explained: 'Even a single paparazzi can turn into 50 paparazzi and ruin an entire day. I think everyone in my family has thick skin and everyone handles the paparazzi differently, but Kendall's the one kid who's so sensitive towards it. It really brings her down and I always feel so bad when she feels trapped.'

Kylie later told Khloe: 'I'm over not being able to go out and be normal for a second. Life is life but sometimes I just want to be a kid. I can't remember what it's like to go out and nobody know who I am.'

After hiring a rental car and stopping off for a Subway sandwich, the Kardashian clan made their way to the Ultimate Hollywood Tour bus to take in the celebrity sights, but it did not take long for a photographer to spot them.

While Kendall freaked out and claimed it was 'embarrassing', Khloe insisted they carry on with their experiment.

Snapchatting at the back of the bus to leak the story before the paparazzi photos got out, the girls laughed and told the driver it was their first time in California.

When asked whether they had flown or driven, Khloe said: 'Oh I can't go on a plane. I've got metal pins all in my legs and a bad hip.'

'That's not true,' Kylie and Kendall shouted.

After fans spotted them from a passing car and shouted Kendall's name, the driver asked whether they were YouTube stars.
