Justin Bieber and Selena Gomez Crash a Wedding

As far as unexpected wedding presents go, it doesn't get much better than a surprise visit from Justin Bieber and Selena Gomez.

SG and the Biebs were taking a stroll down a Malibu beach over the weekend when they heard one of Justin's songs coming from a nearby wedding reception and decided to stop by and congratulate the happy couple.

According to witnesses, Biebs "took the microphone, congratulated the newlywed couple, and said a few nice words, while posing for a series of pictures with his fans." Justin and Selena only stuck around about ten minutes, but they no doubt made it a wedding to remember for everyone in attendance. Although next time, it wouldn't hurt to bring and envelope full of cash. Just sayin'.
