John Cena's Wife -- You Can't Divorce Me ... Yet

John Cena's wife REFUSES to let the wrestler file for divorce -- at least the way he's doing it now -- and to prove she means business, she's asking a judge to throw out the WWE legend's divorce papers.

Elizabeth Cena just filed legal docs in Florida, claiming John's recent divorce petition is riddled with errors ... and should be dismissed.

According to Elizabeth, John inaccurately refers to her by her maiden name (Huberdeau) instead of her legal name (Cena). As a result, Elizabeth says John fails to bring "a proper dissolution of marriage action" against her.

Elizabeth also claims John failed to attach the prenup he references in his initial divorce filing -- a copy of which MUST be attached in order for the filing to be valid.

Elizabeth also takes issues with John's claim that there's no marital property -- Elizabeth insists there is ... and she wants her share.

For all these reasons, Elizabeth wants a judge to dismiss John's petition and force him to re-file ... if he dares.
