Jay Z, 44, and his pop star wife Beyonce Knowles apparently do not like appearing on reality shows, reported Daily Star.
"Jay is Kanye's closest friend so he wants him to be best man. Jay agreed initially but had one condition - under no circumstances can there be any reality TV shows filming him, his wife, Beyonce or daughter Blue Ivy during the ceremony," a source said.
Recently it was rumoured that the socialite would be marrying West on May 24.
