Usher and longtime partner Jenn Goicoechea married in Las Vegas just hours after the R&B superstar's headline appearance at the Super Bowl halftime show, according to officials and documents. The officiant who wed the pair is known to dress as an Elvis Presley impersonator, The Associated Press reported. The couple married Sunday at Vegas Weddings, according to a marriage certificate made public Monday. The ceremony was officiated by the Rev. Ronald Joseph Polrywka, better known locally as Ron DeCar. Witnesses included Jonnetta Patton, Usher's mother.
