Despite not letting the cameras in for the actual ceremony- taking place in France - Kim is allowing E! to film 'everything leading up to and after' the big day.
'She's taping everything else so she can get things for free in exchange for the exposure,' a Kardashian source told the magazine.
Another insider added: 'They realised how much their wedding was costing, so they told E! they wouldn't allow parts of it to be taped unless the network offered them more than $15 million, which is what Kim got for her wedding to Kris [Humphries].
'Her mom couldn't help herself either. Kris is trying to get them another $4 million for their wedding photos.'
Kim was back in reality star mode at the weekend as she filmed her Parisian themed bridal shower for Keeping Up With The Kardashians at Beverly Hills' Penninsula Hotel.
But even then, the guests' 'decadent food, drinks and goodies' were 'paid for or sponsored by brands that wanted exposure' reported an In Touch source. 'E! picked up the rest.'
The famously extravagant couple's wedding will certainly not come cheap with airfares, couture dresses and expensive gift bags all adding up, so it's no wonder that Kim hopes to minimise her outlay.
'Kim made millions off her last wedding on top of everything that was paid for,' the source said. 'She understands the business of having a televised wedding.'
Having been married twice - to Humphries and music producer Damon Thomas, Kim has surely learned how to best work a wedding to her financial advantage.
Indeed the ceremony with Humphries would have cost them $10 million if they'd had to pay for their freebies before it netted them $18 million.
