Kristen Stewart and Robert Pattinson helped a lucky New Jersey couple celebrate their big day this weekend.


The on- and off-screen couple – along with Zac Efron, Andrew Garfield (sans girlfriend Emma Stone) and Will Kopelman (sans wife Drew Barrymore) – made their way to Englewood, N.J., where Hollywood producer Kevin Turen wed Evelina Oboza on Saturday.


"They stuck to each other's side all night," an attendee tells
PEOPLE of Stewart, 22, and Pattinson, 26, who partied with guests until
dawn and were spotted walking hand-in-hand during the celebration.


And the bride wasn't the only one (likely) wearing something borrowed.

Before heading to the wedding, Stewart realized she forgot her dress. The solution? The Twilight
actress strapped on a short, navy Zac Posen cocktail dress from the
groom's sister Ashley's closet (that matched her Christian Louboutin
shoes just fine).


By the end of cocktail hour, however, she was back in her own
wardrobe – jeans, a black tank top and a blazer – as she mingled with
fellow guests.


Although Stewart didn't show off the moves she put on display during her Twilight
wedding, a date-less Efron, 24, tried his hand at the hora, a
traditional Jewish dance, before hanging out with mainly male partygoers
for the evening. And Pattinson got in the groove manning the deejay's
laptop for a bit.


Meanwhile, a dapper Kopelman kept it friendly, often mentioning "my wife" when he chatted with female attendees.


Other special guests: Harry Morton, Sarah Roemer and Tovah Feldshuh.


After spending the night at the groom's house, Stewart headed to
Paris for a photo shoot and Pattinson flew back to Los Angeles. Efron
kicked back by the pool Sunday until after dinner.
