Their child, who is expected in the very near future, will become 'a future reality star and a social media star', according to the former The Hills star in a new interview with The Sun.
'We've already locked in his Instagram, his Facebook, his Twitter,' Spencer said, adding: 'We don't need Snapchat because he has Instagram stories.'
Pratt, 34, also says his son will have some of the latest technology upon his arrival.
'I didn't want him to have the iPhone X and get overwhelmed, I have the x though. So his is just an 8.'
Montag, 30, has not confirmed if her husband's claims are true or were just made in jest, but did retweet the article in which they were made.
Despite setting their son up for social media stardom, Pratt hopes their son's first photo will be shared in a more conventional manner.
He said: 'He won't be making his debut on Instagram or Twitter - hopefully a tabloid cover, that's the dream.'
In a video shared to social media earlier this week, Spencer had a pep talk with his wife's baby bump, urging their son to stay unborn a little bit longer.
'Listen up, son, I know you can hear me. Khloe Kardashian is now pregnant. That means you really cannot come out early, at least one more week', he said while giving a pep talk to his wife's stomach.
'She's gonna have all the tabloid covers next week, son. Don't blow this, okay? I'm depending on you.'
