    "I do" wish I'd scored an invite to this supremely star-studded wedding!

    Over the weekend, Robert Pattinson and Kristen Stewart attended a New Jersey couple's nuptials, and the Twilight twosome weren't the only A-listers in Englewood. Zac Efron, Andrew Garfield and Drew Barrymore's new hubby Will Kopelman were also in attendance, a source tells E! News.

    Pattinson, 26, didn't just nosh on wedding cake and hang out: He hung out with Talent Resources CEO Mike Heller and played part-time DJ for the fête! Singer Matt White tweeted a photo of the actor intently focused on a MacBook, presumably picking out the next song for producer Kevin Turen and his bride Evelina Oboza's wedding.

    A source tells E! News that Pattinson and Stewart "arrived holding hands and kept close much of the evening." They were, however, spotted mingling with guests throughout the evening.

    Pattinson donned a charcoal suit and tie, and Stewart wore a silk ensemble for the ceremony and recpetion. Later in the night, she slipped into jeans, a black tee and charcoal blazer.

    Zac Efron didn't bring a date, but he adorably tried dancing the hora, a traditional Jewish dance. Andrew Garfield was also in attendance, but girlfriend Emma Stone did not accompany him.

    And although Kopelman didn't have Barrymore by his side, he reportedly name-checked "my wife" in several conversations with female guests.

    The party went on until around 5 a.m., and because of the high-profile guests in attendance, extra security was on hand just in case.
