Michelle revealed that it took around a month to plan the raucous Essex do. The actress, who is from Stockport, arranged for her friends and family to come down from Manchester while Mark's loved ones were all, naturally, in on the secret.
In this week's HELLO! Online blog post, Michelle wrote: "Initially he knew about there being a party getting planned, but around Christmas we cancelled the venue because he thought he would be away with work, but the plans changed and cunning little me re-booked everything – without telling him! Mwahahahah!"
Michelle spent a month planning Mark's surprise party
She added: "All my family from Manchester – mum, dad, aunties, cousins, all my school friends and their partners all travelled down, and were part of the surprise. All of Mark's family and friends were in on it too of course."
The group let their hair down and sipped on tiki-themed cocktails, before indulging in Mark's incredible birthday cake that had nods to Mark's passion – football – and his day job – presenting on Heart radio.
The cake "provided a real wow factor on the night", Michelle wrote, adding: "Mark LOVES his sweets, hence the sweet theme." A DJ flew in especially from Majorca, while Mark's family friend also hit the decks.

The couple celebrated Mark's milestone birthday with a whole host of festivities. They were in Florida ahead of Mark's actual birthday, and went out for a special date night. Sharing a photo of the loved-up couple, the former TOWIE star wrote on Instagram: "Tipsy, Pre birthday celebrations last night."
A couple of days later he followed it up with another post, again sharing a photo of his birthday drinks. "Cocktails out again.... proper milking my birthday!!" Mark wrote.
