'Gangnam Style' Wedding: Danny Rose Marries Aaron Rosenberg, Singer Psy Performs

Surprising your guests with a "Gangnam Style"-dance at your wedding is all the rage right now, but nabbing "Gangnam Style” crooner Psy as your wedding singer? Now that takes the cake.

On Saturday, “Cougartown” producer Danny Rose and Hollywood entertainment lawyer Aaron Rosenberg did just that, bringing the K-Pop superstar to Hollywood to entertain guests at their lavish, star-studded wedding reception.

The party, held at LA’s Paramount Studios lot, began with the grooms riding in on a white horse complete with a unicorn horn, as Madonna’s “Like a Virgin" played, the New York Post reports.

Psy’s surprise performance was a gift to Rosenberg from music manager Scooter Braun, according to the Daily Truffle, though the viral singing sensation had some competition; the grooms and guests -- including "Cougar Town" stars Courteney Cox and Busy Philipps -- were also treated to performances by John Legend, Ciara and Joss Stone. Meanwhile, an absent Jennifer Lopez sent the grooms a pre-taped video tribute from her concert.

Rose proposed to Rosenberg earlier this year, releasing a proposal video and a song on iTunes to raise funds for marriage equality charities.

Is it just us, or does Rosenberg and Rose's backlot bash sound like the best wedding reception ever?
