Justin Bieber and Selena Gomez spontaneously crashed a wedding reception at the Adamson House in Malibu after they heard Justin's song "One Less Lonely Girl" being played there while they were strolling on the beach.
Justin first met with some very surprised but lucky guests and then went up to the microphone and announced their presence.
"What's up everybody," he greeted the guests.
"We just crashed it. We heard a party so we decided to just come. So let's party."
The cute teenage couple stayed at the wedding reception for 10 minutes during which they posed with the bride and groom, Rob and Jeanine McCool.
TMZ has a video of Justin interacting with the guests, talking on the microphone and posing with the lucky couple.
Here is a YouTube video.
