Beyoncé Knowles avoiding Kim Kardashian's wedding?

Beyoncé has reportedly agreed to attend Kim Kardashian's wedding to Kanye West only if she is excluded from filming for Keeping Up With The Kardashians.

The singer who married rapper Jay Z in a private ceremony in April 2008, has reportedly said that she thinks its "tacky" that the couple are planning to show their nuptials on Kim's E! show but has agreed to attend the ceremony as long as she isn't filmed.

A source said, "[She told Jay Z and 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.

Jay and Beyoncé'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. She knows she'll have to go to the wedding, but really does not want to." Kanye is said to think of the A-list couple as his family. The source added, "Make no mistake, the only reason Beyoncé is going to the wedding is because Jay is best friends with Kanye."
