Singer Beyonce Knowles may not attend Kim Kardashian and Kanye West's much-hyped wedding.

Beyonce thinks it's extremely tacky that the nuptials are going to be filmed for the reality show `Keeping Up With The Kardashians`, reports radaronline.com.

The 17-time Grammy Award-winner has told husband Jay Z and his best pal, Kanye, that `under no circumstances will she be a part of any filming on the wedding day if it's for Kim's reality show,` said a source.

`Jay and Beyonce's wedding was shrouded in secrecy and extreme lengths were made to make sure their wedding was an intimate affair for friends and family, only. This will be the complete opposite. She thinks it's just tacky.

`Beyonce's motto has always been, less is more. But clearly when it comes to Kim, more means more. She knows she'll have to go to the wedding, but really does not to want to,` added the source.
