Vegas casino/real estate kingpin, Steve Wynn, and his fiancée, Andrea Hissom, decided to train for their big day by throwing a fake wedding ceremony at the Cupid’s Wedding Chapel in Las Vegas, Nevada over the weekend (more pictures below).

The 69 year-old dressed up like the King, Elvis Presley, and celebrated with his younger bride, 46 year-old divorcee and mother of two teens, dressed as Lady GaGa. The real wedding is set to take place at the Wynn Chapel on Saturday morning (April 30).

Some have drawn comparisons between Steve’s wedding and the big Royal Wedding (on Friday, April 29), but Steve says his wedding is all about fun. The three day wedding extravaganza will count with several celebrity guests, including Clint Eastwood who will be the groom’s best man.
