Pattinson and Garfield who are both from England were able to bond with Zac Efron in a very unique way. According to Hollywood Life reports, Robert Pattinson hopped on stage during the party to sing a couple of songs to the other guests with the other two actors. "There was a little area where you could go and play music," a guest at the wedding explains.

"Rob sang, Andrew played the bongos and Zac played the guitar. It was a whole spectacle!" the guest revealed. Zac Efron must have really enjoyed the party. "He was rapping towards the end of the wedding. It was hysterical!" the guest further shared.
