PHARELL MARRIES LONGTIME GIRLFRIEND & USHER PERFORMS AT CEREMONY

Love is in the air again this weekend, and in the words of "Blurred Lines"..."Everybody get up"! The triple threat singer/songwriter/record producer, who goes by just his first name, wed longtime girlfriend Helen Lasichanh on Saturday.  The couple are already parents to a son, Rocket, 4.

Pharrell co-wrote and produced Robin Thicke‘s megahit, “Blurred Lines,” and performed with him on the record and in the super-sexy video.  Surprisingly, Thicke reportedly did not attend the ceremony.

 But Usher and Busta Rhymes put on a mini concert, a source told Us Weekly. "It was so fun. The little concert was amazing. It [was] the most fun wedding I've ever been to."
