William and Kate aren't the only people having a lavish wedding next weekend. Las Vegas hotel king Steve Wynn is marrying Brit beauty Andrea Hissom during a three-day blow-out with an estimated price tag of well over $1 million.

Wynn -- think the Mirage, Bellagio, Wynn and Encore resorts -- is flying in many of his famous friends, according to The New York Post. Garth Brooks, Donald Trump, Hugh Jackman, Sly Stallone and Vegas local Celine Dion are all expected.

High School Musical director Kenny Ortega, who was also the director for Michael Jackson's ill-fated final tour, will be orchestrating Saturday night's Grand Celebration for 1,000 guests.

Wynn married and divorced first wife Elaine twice. Her 2009 settlement was a reported $741 million, believed to be one of the world's biggest.  Wynn and Hissom met while vacationing on the French Riviera in 2008.
