Pop music icon Taylor Swift surprised a couple - and their guests - at the Brant Beach Yacht Club on Long Beach Island Saturday.

According to sources, the groom's sister contacted Taylor and helped set the whole thing up, keeping it a complete secret from the happy couple.

Taylor sang and posed for pictures, even posting her own pic on Instagram, congratulating the couple, Max and Kenya. Pretty cool.
