Mark, who starred in the ITV2 reality show himself until last year, was said to be "filming overseas" when the lavish outdoor ceremony in Essex took place.
Mark's parents, 'Big' Mark and Carol, were joined by their daughter Jessica - who serenaded them by singing - and two younger children Natalya and Josh.
Even Nanny Pat was present in all her finery, so it was no doubt a blow not to have Mark and his Coronation Street star girlfriend Michelle Keegan there to witness the momentous occasion.
When asked why Mark wasn't present, a TOWIE spokesman told Reveal: "Mark was actually filming for another show overseas so couldn't attend."
Although Mark didn't reunite with his cast mates, former TOWIE star Debbie Douglas made a return to the ITV2 show on Sunday night (7 July).
Debbie joined the other TOWIE ladies in throwing Carol a hen night to remember!
