Las Vegas hotel king Steve Wynn married British beauty Andrea Hissom Saturday in a lavish, private ceremony, reports the Las Vegas Review Journal. Clint Eastwood served as best man, but he wasn't the only star in attendance.
Also at the ceremony among the 500 guests at the Wynn Las Vegas Chapel were Lionel Ritchie, Sylvester Stallone, and Céline Dion. Garth Brooks was also there to perform some songs at a party on Friday night.
The old-Hollywood-themed reception was held in the Encore ballroom, and featured performances by Trisha Yearwood (who also sang a duet with hubby Garth) and Grey's Anatomy star Sara Ramirez.
The billionaire entrepreneur and Hissom started dating in 2009.
