That's according to The Mirror, anyway, which claims those invited to the bash will be photographed during the ceremony and reception as well as breakfast the next day, as part of an exclusive magazine deal.
A source said: "The venue Mark an Michelle have chosen is incredibly posh – it's like somewhere Lady Edith [fromDownton Abbey] would get married. So guests attending the breakfast the following morning will still have to look swish."
Michelle and Mark have been pretty tight-lipped about their actual wedding, declining to even reveal the date or venue, although it's widely tipped to be at Hengrave Hall in Surrey later this month.
The couple became engaged in Dubai in September 2013.
Both have recently returned to the UK from celebrating their hen and stag dos abroad: Michelle and her girls enjoyed a trip down memory lane in Dubai, while Mark and his pals jetted off to Las Vegas.
Although details of the whole wedding are being kept secret, we do know that bridesmaids will include Mark's sister Jessica Wright, who currently stars on TOWIE.
We also know Lydia Bright is invited as she tweeted and deleted the couple's beautiful wedding invite earlier this week! Although, that's not really a surprise given she's dating Mark's best mate James 'Arg' Argent!
