Justin Bieber and Selena Gomez Crash Malibu Wedding!

While not everyone can say their wedding was the best day of their lives, for one lucky couple, it will ring true even if things don't work out. This past weekend, pop sensation Justin Bieber and singer girlfriend Selena Gomez decided to crash Rob and Jeanine McCool's wedding, and it's caught on video! Most brides would be more than miffed to let anything or anyone outshine her on her wedding day, but I'm sure this bride took exception.

According to a cousin of the new couple who posted the video below, Bieber overheard the reception karaoke-ing his song "One Less Lonely Girl" (appropriate wedding song) while driving by and pulled over to see what the scene was about. In true form, he caused a riot among the flabbergasted guests and happily posed for pictures with guests and the bride and groom. Gomez, playing patient girlfriend, stayed to the side during the commotion and waited for Bieber by his car. The appearance only lasted about ten minutes, but like all weddings, the memories will last a lifetime.

Now this makes us think: Was Justin in need for a little fan pick-me-up? Why would he take the time to actually stop his car, park, get out and search the venue, following the sweet sound of his own melodies? Seems a little tedious for this writer, but whatever the reason, it was a very sweet gesture from the popstar and the McCools now have one of the greatest wedding stories ever to tell. So Beliebers across the world, break out your karaoke machines and start singing. Like a siren's song luring fishermen to the sea, your rendition of your favorite Bieber song might just catch Justin himself.

Justin Bieber's Pal President Obama Introduces Him To 9/11 Teens

Justin Bieber is right. It's best to keep an optimistic outlook and to "never say never."

Justin fan Payton Wall's dream came true last week when she met the teen idol, the result of a favor from President Barack Obama who promised to facilitate an introduction to the pop star after receiving a 1,500-word email from the teen, whose father died on 9/11.

Payton said Justin's documentary "Never Say Never" helped her cope with the loss of her dad, Glen James Wall, who was a Cantor Fitzgerald executive who worked in the twin towers. Payton, her sister Ashley, and her friend Madison Robertson -- whose father Donny Robertson also worked for Cantor Fitzgerald and died on 9/11 -- met Justin last week during the pop star's stop at Macy's in New York's Herald Square to promote his new fragrance, Someday.

"It was so cool. I couldn't even believe it," Payton told the New York Post. "He said, 'Hi.' He was asking us about the perfume and if we were wearing it."

"He was really nice and is so cute," Ashley said. "He didn't even look real."

Payton was surprised when Obama replied to her email. "I never thought he'd respond," she told the Post in May. "I was so shocked when the White House called! It was all a dream come true." Payton had previously sent a message to Justin via Twitter and also letters to Hollywood executives to no avail.

Payton said Justin's life story, as chronicled in "Never Say Never," made her want to share her own hardships. "We were so amazed by his story and how he never said never," she said. "It inspired us to believe in ourselves and share our story to encourage others."

Obama received Payton's letter the day after Osama Bin Laden had been killed. Moved by Payton's personal story, Obama invited the teen, her mother, and sister to the Ground Zero ceremony in May.

When meeting Obama in person, Payton again inquired about meeting Justin, and the president said he would help.

Payton said she didn't just write the letter in hopes of meeting the "Baby" singer. "I did it to honor my father," she said. "My father is the reason that we all came together today. I miss and love him and don't go a day without thinking about him."
