So it’s your wedding reception and one of your pals is up doing his best Justin Bieber impression on karaoke. Prolly the last person you’d expect to show up at that very moment is the Biebs himself… and yet that’s exactly what happened at the wedding of Rob McCool and Jeanine Holguin in Malibu!

Apparently Selieber were having a romantic stroll on the beach when they heard One Less Lonely Girl and decided to mosey in. Unforch they didn’t hop on the karaoke machine themselves but met the bridal party for a few quick snaps. How blimmin’ sound are they?
