The private Twilight pair were joined by Zac Efron, Andrew Garfield, and Drew Barrymore's new hubby Will Kopelman at the star-studded nuptials in New Jersey, where Hollywood producer Kevin Turen married Evelina Oboza.
'They stuck to each other's side all night,' one attendee told American magazine People of Robert Pattinson and Kristen Stewart, who danced with guests until dawn, and were even spotted strolling hand-in-hand during the celebration.
But according to reports, the day wasn't all plain sailing, with Kristen forgetting one all-important item: her dress.
According to insiders, the bride's sister stepped in and saved the day, loaning lucky Kristen a short, navy Zac Posen number from her own wardrobe to watch the couple walk down the aisle.
True to form, Kristen whipped her posh frock off at the earliest opportunity, changing into jeans, a black t-shirt and black jacket for the evening celebrations.
As the crowd partied into the night, Rob took a turn on the DJ decks, and was even snapped hard at work choosing tunes behind on Apple laptop.
Meanwhile, Kristen mingled with fellow guests, and watched Zac Efron try his hand at the hora, a traditional Jewish dance.
