The Duchess, 31, decided to check out the reality programme after hearing that Kim, 32, was a big fan of hers and now she's hooked on the family's antics.
'Ever since Kim started mentioning Kate a lot in public, the princess has started watching Keeping Up With The Kardashians religiously,' says a source.
'She thinks the family are hilarious. People forget that Kate is just a normal girl, who married into royalty, and enjoys the same trashy TV shows most people do.'
Kim, 32, has spoken about how much she admires Kate on a number of occasions and is said to be 'thrilled' that both of them are expecting their first babies in July.
Despite Kim having something in common with his wife, Kate's husband Prince William, 30, can't be persuaded to join her on the sofa when Keeping Up With The Kardashians is on.
'Will doesn't watch the show with her, and makes fun of her for liking it so much,' the insider tells the Daily Star.
'It doesn't bother Kate, though. She finds it relaxing, and is flattered Kim keeps speaking so highly of her.'
