Kim Kardashian is reading philosophy to impress her boyfriend Kanye West.

The 'Keeping Up With The Kardashians' star has been getting to grips with 19th Century philosopher Friedrich Nietzsche because she knows the 34-year-old rapper is a fan.

A source told The Sun: "Kim's desperate to show Kanye she's not some kind of bimbo, so she's reading up on Nietzsche as Kanye says he's a huge inspiration of his.

The 31-year-old star is also staying up to date with current affairs in order to seem more knowledgeable to her new music producer partner.

The insider continued: "She's making sure she reads the papers and the news every day and has downloaded the CNN app on her phone to keep up to the minute."

Kim is additionally said to be experimenting with painters so she can chat to Kanye about his love of all things art.

Friends say she has just employed an art dealer to put in a bid for an artwork by graffiti artist Jean-Michel Basquiat - whose other fans include U2 frontman Bono and 'Fashion Star' presenter Elle Macpherson.
