Rapper Kanye West is reportedly upset with his fiancée, American reality television star Kim Kardashian, after discovering she had a relationship with singer Chris Brown.

According to Radar Online, the 36-year-old singer is so jealous that he might even call off their wedding if Kardashian talks to Brown again.

The couple are scheduled to walk down the aisle in Paris on 24 May, less than two weeks before West's 37th birthday.

"Even though the encounter between Kim and Chris happened long before Kanye came on the scene, being Kanye, he's still intensely jealous," a Kardashian insider said.

"There were definite sparks, but she insisted to Kanye that nothing happened between them. That hasn't stopped Kanye from having a major jealous meltdown," the source added.

Adding on, West dislikes Brown more because he attacked his then-girlfriend Rihanna after a pre-Grammy bash in 2009.

"Kanye intensely dislikes Chris because of what he did to Rihanna," the source said.

"He's obviously someone Kanye doesn't believe he and Kim should have anything to do with," the insider continued. "Especially now with their Vogue cover, Kanye knows he and Kim are an A list couple who don't need to be tainted by associating with Brown in any way, shape, or form. Kanye gave Kim a stern warning to avoid him in the future!"

Brown was first linked to the Keeping Up With the Kardashians star back in 2010 after Media Take Out ran a story claiming that Rob Kardashian hooked them up.

Kardashian denied the dating rumour at the time tweeting: "I have to say , I literally laughed out loud at these dating rumors today! Come on now MTO, I literally can't keep up anymore, not true!"
