The 30-year-old, who recently married Kris Humphries, said that looking at the Best Thing I Never Had singer's body has inspired her to work out more.
Kim told British New! magazine: 'It's no secret that I'm a huge admirer of Beyonce.
'She has one of the best bodies in showbiz and it motivated me to work out. And all of her albums are memorable, I just couldn't possibly choose a number one.'
As well as being a big fan of the pop star, who is currently expecting her first child with her husband Jay-Z, Kardashian also admires George Clooney.
She added: 'Who doesn't have a soft spot for George? I love all the characters he plays. He's a timeless actor who has an amazing ability to make a good movie even better.'
