The couple crashed the wedding of Rob and Jeanine McCool after hearing Bieber's "One Less Lonely Girl" blaring from the reception, held at Malibu's historic Adamson House.
According to reports from TMZ, Bieber and Selena keep their drop-in a short one, merely popping in to suprise guests (even the male guests couldn't help but shriek) and pose for a few photos. One attendee guest captured the interaction, which started with Bieber hopping on the mic to announce, "We just crashed it. We heard a party so we decided to just come. So let's party." Watch below.
Rob and Jeanine McCool, congratulations on your wedding -- and on making pre-teen girls everywhere supremely jealous.
