Talk about welcome wedding crashers! Gossip Cop reports that Justin Bieber and Selena Gomez made a surprise appearance at two strangers' post-nuptial reception, after the wedding DJ played Justin's "One Less Lonely Girl" for the gathered guests. No, it wasn't a planned cameo; the pair overheard the song during a nighttime stroll on the beach and decided to see where the music was coming from. The two popped in, posed for pictures with the newlywed couple and their guests, and then politely took their leave. (No word on whether they stayed long enough to eat cake.)
Meanwhile, we couldn't help thinking about which other celebrity couples we'd love to have as surprise, uninvited guests at one of the 3 million weddings we have to attend this summer. For instance...
Katy Perry and Russell Brand: You know these two would bring some serious energy to the party...not to mention an endless supply of sequined latex leotards as a tasteful alternative for the suffering, fuchsia-taffeta-covered bridesmaids.
Nina Dobrev and Ian Somerhalder: We're pretty sure they're an official couple, but we'd like to get a nice, close look at 'em for confirmation. Preferably while dancing next to them during the Electric Slide.
Kristen Stewart and Robert Pattinson: Forgotten vows? Torn dress? Intoxicated brother-in-law making the world's most embarrassing speech? No worries! One appearance by the elusive KStew and RPattz, and nobody will ever remember.
