Sources close to the planning of the ceremony tell The Blast around 250 guests have been invited to Graffiti Mansion in Sin City to see the unification of Jana.
Among the crowd will be 50 of the biggest influencers on social media today, including Jake's brother, Logan Paul.
Many of those guests will be arriving via private jet into nearby McCarran International Airport, and then receive car service to the exclusive event.
We're told along with a private security force, the Las Vegas Metropolitan Police Department has been notified of the event.
After the ceremony, which takes place on Sunday, we're told 80 limousines will shuttle the guests over to the Sugar Factory at Fashion Show on the Vegas Strip.
We're told the PD has also been informed of the large caravan scheduled to make their way down the strip.
As for the newlyweds, we're told they will be cruising to the reception in a "classic American car."
We're told the Sugar Factory has planned an amazing party for the stars, including a "Candyland" themed venue with multiple rooms to stimulate the senses and taste buds.
Among the treats being assembled include an open candy bar and two wedding cakes -- one being 7 tiers!
The color themes are spearmint and pink, which will also be reflected in the food. We're told Sugar Factory is even whipping up a batch of pink and green sliders.
There's no telling what type of craziness will go down at the stars' wedding ... but just as they promised, it will definitely end up on YouTube.
