Beyonce's record label bosses have come to the R&B superstar's defense against allegations she pulled out of a nightclub show, insisting she never agreed to perform in the first place.

The Crazy In Love hit-maker has been threatened with a $1 million lawsuit by Joey Morrissey over claims she scrapped plans to sing at his M2 club in New York last Saturday. Morrissey alleges he agreed to pay Beyonce $200,000 for the gig, but it was axed four days before it was scheduled to take place because she was preparing for the opening night of her U.S. tour on Sunday.

The club boss told New York Post gossip column PageSix, "They said they were too busy with the launching of the tour and that they wouldn't have time to do the kickoff party. We sold tables for thousands of dollars for the show, and spent $100,000 renting a soundboard and other equipment, as per their stipulations... They've been totally unwilling to agree to another show."

However, executives at Beyonce's label Music World/Columbia Records are adamant it is Morrissey's fault for falsely advertising the show with a performance by the beauty - instead of her sister Solange, who was due to sing at M2.

A company spokesperson says, "Beyonce never had a contract with the club itself and no one in her camp dealt directly with the venue. The superstar was never scheduled to perform, but was to serve as a co-host and introduce singer/songwriter Solange's performance. Patrons were falsely promised a performance by Beyonce."

Beyonce kicked off the latest leg of her I Am... world tour at the Big Apple's Madison Square Garden on Sunday, when she was joined on stage by her rapper husband Jay-Z.
