Beyoncé reportedly thinks Kim Kardashian and Kanye West's wedding will be ''tacky''.

The 'Drunk In Love' hitmaker - who married rapper Jay Z in a private ceremony in April 2008 - has reportedly claimed that she thinks its ''tacky'' that the couple are planning to show their nuptials on Kim's E! show ' Keeping Up With The Kardashians' 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'' and Beyoncé has agreed to be there for him rather than Kim.

The source added to ''Make no mistake, the only reason Beyoncé is going to the wedding is because Jay is best friends with Kanye.''
