The cousin of the bride posted images of Bieber and Gomez on YouTube. He says the two young stars were passing by just in front of where the reception took place when they decided to stop there.
Justin heard that one of his tubes, One Less Lonely Girl, was karaoked at a wedding nearby. He and Selena decided to invite themselves to the party.
A source also told Perez Hilton that Bieber took the microphone, congratulated the newlyweds and agreed to be photographed with the bride and groom and some guests.
Gomez waited off to the side.
Later, the Canadian singer tweeted about the experience: “WEDDING CRASHERS last night. hahaha. too funny. crazy story.”
