If I were Jade I would be doing exactly what she has done for her kids.
As much as I think Max Clifford is a exploitative sleazebag, he has offered her a last chance to make a small fortune for her kids. What parent wouldn't take advantage of the situation?
I don't know why she is marrying that twat though, AFAICS he is marrying his way to her fortune.
Just saw on C4 news that poor guffawing Jack is so distraught that he and his fuckwit pals traveled to the wedding location dressed in bra and panties.
You can't beat a bit of tact and decorum in these situations.
