Reverend Mose Henney, who conducted the ceremony, is not qualified to marry couples in Sin City, officials claim.
If confirmed, this would mean Jordan, 31, is not Mrs Alex Reid and their union is void.
Reverend Mose Henney, who moved to Las Vegas after quitting the Lutheran church in Wisconsin, did not have the relevant licence to conduct weddings, it's claimed.
'You've got to be kidding,' he told The News Of The World. 'This is something I need to straighten out.'
Jordan divorced Peter Andre, 36, last year. They are parents to Junior, 5, and Princess, 2.
She is also mum to Harvey, 7, with Dwight Yorke.
