The husband and wife-to-be won't be serving their guests anything fancy and instead will be sticking to their roots, it has been reported.
A source told The Sun: "They are both incredibly proud of their roots and want to celebrate where they came from."
The newspaper reports that guests at the celebrity wedding of the year will either be tucking into pie and mash or fish and chips.
Michelle, 27, recently discussed her and 28-year-old Mark's plans for the big day.
Talking about her wedding dress on This Morning, she said: "Yes [I've sorted the dress], so that's the main thing done I suppose!
"And most of the things are sorted now… it's just tying up a few loose ends.
"[Mark's] really hands-on, yeah. It's annoying! I didn't want him to have the opinion! It's been good, we've been a team."
Mark and Michelle, who have been together since January 2013, are due to get married in late May, at a Tudor mansion in Bury St. Edmunds.
When asked about her and Mark's hen and stag parties, Michelle revealed: "We are having a couple.
"We are having a few here, for me, and then for Mark, and then couple abroad as well – one each. I'm already saying too much! I just want to say everything, I get really excited."
