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.
Zac Efron spends most of his time barely dressed in the movie Paperboy, but he was fully clothed – and ever so dapper – when he made it out to the afterparty in celebration of his film.
The bash, hosted by Ciroc Vodka and skincare line Erno Laszlo, was also attended by costars Nicole Kidman and Matthew McConaughey, along with Kidman's hubby Keith Urban and Reese Witherspoon. And guests were treated to elegant affair, despite the gritty nature of the movie being honored.
The event was held in a white lily-filled vintage lounge on Carlton Beach in Cannes, where guests sipped vodka and noshed on "every flavor of macaroons," according to a party-goer.
Jennifer Aniston was in a bright, sunny mood while hanging out with boyfriend Justin Theroux at West Hollywood's Chateau Marmont, an onlooker tells us. The couple seemed "content and present with each other" even as they were hanging out with a big group of people in the back area of the hotel's patio.
Aniston was bundled up for the weather, sporting a black wool peacoat and black pants, while her actor beau was in a leather jacket and gray T-shirt.
Theroux also greeted fellow revelers on the patio, sharing a hug with fellow guests like Zac Efron, who was there to hang with some guy friends. But when it was time to go, he only had eyes for Aniston, and the two giggled together as they left. Says the observer: "She and Justin were beaming and seemed enamored of each other."
Also at the Chateau that night: Eva Longoria, who was celebrating her 37th birthday with friends; and an energetic Lindsay Lohan who arrived at the hotel after midnight with one guy and a blonde female friend.

Rumer was more into the club scene, though, climbing atop the banquette to dance to the tunes – specifically AC/DC's "You Shook Me All Night Long" – and sticking around well after Efron, who left before his pals. – Jennifer Garcia
