The 'Charmed' star, who married artist Davey Detail on October 12 last year, has been sued by DJ Nahchey Storer in a small claims court, reported TMZ online.
The wedding DJ has claimed in his lawsuit that he was hired by McGowan, 40, to perform at her wedding last October, but she cancelled him at the last minute and stopped the payment on his check.
The DJ said he had a written contract with McGowan and wants full payment of USD 4,262.
