JB and Hailey then treated everyone to dessert which included ice cream and carnival items while the group watched a screening of 'The Notebook.'
We're told earlier in the day, a crew of celebrities and friends played a game of touch football, literally like a scene out of another movie, 'Wedding Crashers.'
Around 1 am, early Monday morning, Justin and Hailey surprised everyone breaking out huge water guns and blasting all of their friends in the resort. We're told for over an hour, a huge water fight ensued.
As one source put it, the whole thing is literally like a scene of 'The Notebook.' The wedding party booked the entire resort in South Carolina for the nuptials, and the property is 20,000 acres of lakeside beauty.
As for the celebrities in attendance, we're told Kylie Jenner, Kendall Jenner, Travis Scott, Ed Sheeran, Usher and The Baldwins are all at the resort.
The reception will be deejayed by Justin's longtime DJ, and their is a wedding band. But, we're told the mic will be open and some of the massive performers like Travis Scott will take the stage and blast out their hits.
