InstagramScooter Braun's wedding to longtime girlfriend Yael Cohen was without a doubt a star-studded affair.
From the guest list to the performers, the music manager's nuptials had Hollywood written all over it.
So let's go over exactly who attended the swanky affair, and how they stole the show!
First up is none other than Justin Bieber. The pop star, a client of the groom, serenaded the newlyweds after they exchanged their vows to The Beatles' hit "All You Need Is Love."
The Biebs had a band join him in the background and sang from the last row among the guests. And just who was sitting right in front of the crooner? Why, Rita Wilson, of course!
The beloved actress sang along and smiled during the live rendition and cheered on with hubby Tom Hanks as Mr. and Mrs. Braun walked down the aisle and greeted guests.
Sophia Bush was also in attendance at the private event over the holiday weekend and snapped several pics on her Instagram documenting her friend's special day.
But the stars really turned out for the reception shortly following the ceremony.
Ed Sheeran was given the honor of singing during the Brauns' first official dance as a married couple.
Asher Roth later joined him on stage and the two performed a version of Blackstreet's "No Diggity."
But wait, there's more!
Not only did Hanks jump on stage to dance, he sang along during the perma-party favorite, "This Is How We Do It."
Bieber even caught the Oscar winner on video and wrote, "Haha Tom Hanks singing "This Is How we do it" dressed like a Rabbi lol #thatdancetho"
That dance is right...
The Biebs couldn't pass at the chance to be in the same room as Carly Rae Jepsen without singing her huge hit "Call Me Maybe," so the two grabbed a couple of mics and had at it.
One wedding guest Instagrammed a clip from the two singing and wrote, "Carly and Justin drop Call Me Maybe and the world explodes #SYBWedding."
By all accounts, it was a day (and night!) that the newlyweds will cherish forever!
