It's a wedding celebration meant for the big screen!
"After the rehearsal/welcome party ended, the guests were shuttled back via water shuttle to the Montage in Palmetto Bluffs where they had an after-hours party. The party was in the bowling and game room," a source shared with E! News. "Everyone was bowling and taking advantage of the games and was having a really fun time. The night went pretty late."
Perhaps The Notebook screening shouldn't be the biggest surprise. After all, the film has some similarities to Justin and Hailey's big weekend.
