Kim Kardashian reportedly tried to ''initiate an affair'' with Kanye West while she was dating REGGIE BUSH.

The 33-year-old reality TV star has reportedly had her eye on the 36-year-old rapper for a while and even attempted to seduce him during her three-year on/off relationship with the American footballer, which ended in 2010.

A source told RadarOnline.com: ''Kim attempted several times to initiate an affair with Kanye and even was busted by Reggie for it.

''It led to a couple of their short term break-ups.''

Kim and Kanye - who have 10-month-old daughter North together - have only been dating for two years, but they've known each other for much longer.

The source explained: ''Even Kim herself admits that while she loved Reggie, she was obsessed with Kanye because she found him fashionable and exciting in a way that Reggie just wasn't.''

Meanwhile, the couple - who got engaged in October - are set to tie the knot next month in Paris, France, and are reportedly keen to have another child next year.

A source said previously: ''She wants to start trying by the end of the year - even though she hated being pregnant.

''She's so besotted with North that she says she's totally forgotten the awfulness of being pregnant and how much she struggled.''
