According to UsMagazine.com, the 37-year-old MTV star – who is due to marry Minnillo, 30, later this year – told reporters: 'We kind of wrestled with that for a while, for obvious reasons.
'Having done reality TV in the past, I didn't necessarily want to jump right back into it without having thought it through to [sic] great length, and we did.'
He added: 'It's a one-off special; a chance to kind of have a great experience and a great moment in our lives documented on TV, and also for us, to have a great wedding video at the end of it.'
