Justin Bieber is a wedding crasher

UNDATED -- Pop star Justin Bieber is playing the role of wedding crasher.

Bieber and his girlfriend, fellow singer Selena Gomez, were taking a moonlit stroll along the beach in Malibu when they decided to make a pit stop.

The couple heard one of his hits blasting from a nearby wedding reception and decided to drop in. A pair of newlyweds got the surprise of a lifetime when teen heartthrob Justin Bieber crashed their Malibu wedding.

The dance floor was packed while guests dancing to Bieber's hit "One Less Lonely Girl" when the singer himself, and girlfriend Selena Gomez, suddenly dropped in.

Bieber addressed the excited crowd, “What’s up everybody? We just crashed it we didn’t know what was going on. We heard a party and decided to come so let’s party.”

One wedding guest recorded the entire exchange sharing it with celebrity website TMZ.

The 17-year-old talked with guests and graciously posed for pictures with the stunned bride and groom.

Bieber and Gomez definitely gave these newlyweds just one more reason to celebrate.

“Rob, you just met Justin Bieber…what are you gonna do next?” one guest asked the groom.

“I’m going to Disneyland!” the newlywed boisterously replied.

The couple is keeping the musical theme going for their honeymoon. They are heading to Graceland Mansion and don't anticipate any more celebrity sightings except maybe an Elvis impersonator or two.
