Kristen Stewart — and a fairly large percentage of young 'it' Hollywood — went to a producer friend's wedding in New Jersey over the weekend, and, wouldn't you know it, she forgot her dress.

Luckily, though, she's a huge celebrity, and the groom's sister was more than happy to lend Stewart a Zac Posen cocktail dress that just so happened to be sitting in her closet.

Stewart attended the wedding of producer Kevin Turen (An American Crime) and Evelina Oboza, who, it turns out, have quite the famous friends: Stewart's boyfriend Robert Pattinson, Zac Efron, Andrew Garfield, and Will Kopelman (aka Mr. Drew Barrymore) were just some of the big names on hand as the couple exchanged vows on Saturday night.

And any doubt about Stewart and Pattinson's couplehood was put to rest by a lucky attendee who was more than happy to report on the Twilight duo, telling People.com, ""They stuck to each other's side all night."" But both were reportedly not too famous to mingle with the guests — especially Pattinson, who was eager to serve as guest deejay for part of the affair.
