'Spill Your Guts or Fill Your Guts' is probably one of the greatest talk-show games ever and James Corden has finally invited Kim Kardashian to take part during his 'Late Late Show' segment. Surprisingly, she was extremely willing to spill on anything - apart from whether or not her sisters are pregnant.

The game has already seen Khloe Kardashian and Kendall Jenner spill some juicy secrets, so it was about time that the second oldest sibling reveal something we didn't already know. First up: who is the best and worst dressed Kardashian/Jenner sister?

From best to worst we have Kendall Jenner, Kris Jenner, Kylie Jenner, Kourtney Kardashian and Khloe Kardashian. 'She's gonna kill me', Kim says as she reluctantly placed Khloe last.

She was also forthcoming about husband Kanye West's worst habit. Apparently, he's verging on narcoleptic. 'He falls asleep everywhere and it gets really embarrassing when we're in a parent/teacher conference or a doctor's appointment or at a meeting that he's bringing me to to meet fashion designers that I've never met before and he's snoring at a restaurant', said Kim. 'I blame everything on jetlag. Even if he hasn't travelled in like a year.'

She stayed loyal to her sisters, however, refusing to confirm or deny the rumours about Khloe and Kylie being pregnant and instead opting for the disgusting sardine smoothie. She didn't say no though, so that's something...

James, meanwhile, refused to reveal which of his guests was the biggest jerk. 'I know exactly who it is, there is no way on Earth that I'm saying it', he said, putting the scorpion straight into his mouth. He also ate a piece of a cow's tongue rather than choose between his sisters Andrea and Ruth: 'There is no way on Earth I would ever, ever say that one of them is a favourite because I love them both.'

However, he was quite prompt when it came to who his least favourite Kardashian was. 'Easy! Kylie!' He said. 'Kylie Jenner, she pulled out the show. She was gonna come, she didn't come, f*** her, she's the worst.'
