The showbiz wedding of the year is expected to take place later this month, and that means hen and stag parties, doesn't it?
Presenter Mark, 28, has already had one pre-wedding celebration at Faces in Essex, and Michelle, 27, jetted to Dubai with her mates for an 'ultra-VIP' hen do.
Mark's next stop is Las Vegas – but that doesn't mean he and the boys will be getting up to no good.
According to sources, Mark has banned his friends from taking him to any strip clubs.
An insider told the Mirror: "Mark is definitely up for a laugh. He wants to enjoy a drink with his mates and have a dance in the nightclubs and casinos – he just want to go to any smutty clubs.
"He wants good, clean fun, without risking any pics surfacing of him with half-naked girls."
And Mark will be too busy keeping an eye on bestie James Argent, 27, who earlier this year quit the booze after spending Christmas in rehab.
The source added: "Mark has been Arg's number one supporter during his weight-loss process and has encouraged him to live a cleaner, healthier lifestyle. So the last thing he wants is for his messy stag to tempt Arg back to the booze."
