Singer Jay Z may not attend his friend and rapper Kanye West's marriage with socialite Kim Kardashian.

The rap mogul told West that he and singer Beyonce Knowles along with their two-year-old daughter Blue Ivy will miss the nuptials, expected to take place in Paris next month, reports femalefirst.co.uk.

Jay Z and Knowles are uneasy about the fact that the marriage will be filmed for the Kim's reality show "Keeping Up with the Kardashians".

However, to make up things between him and West, Jay Z will throw a lavish bachelor party at his New York club 40/40 for the rapper and is also planning to spend 100,000 pounds on the duo's honeymoon as a wedding gift.

"Jay Z would be there if it wasn't going to be such a public event. Instead he's making it up to his mate by throwing him the most extravagant bachelor party known to man. It will cost a small fortune - and to top it all off, he's chucked 100,000 pounds yacht rental in there as a wedding gift as well," said a source.

It was previously said that Kim and West were so keen for Jay and Knowles to be at their wedding, that they exempted the couple from their strict security arrangements.

"There is no way Kanye would ever even dare to ask Jay or Beyonce to sign a non-disclosure agreement, or take away their cell phones. He knows that neither one of them would betray his trust," said a source.
