The Duke and Duchess of Vegas: Wynn and his British bride Andrea Hissom, ontheir wedding day held at the billionaire's Encore casino on the weekend. Actor Clint Eastwood - said to be the groom's best man - can be seen in the background of the picture
Anything Prince William and Kate Middleton could do, Las Vegas casino billionaire Steve Wynn was trying to do better.
And while his weekend wedding to British sweetheart Andrea Hissom was no Royal occasion, the casino king and his bride clearly did their best to match the event of the year.
With her elaborate lace sleeves and plunging neckline, it was almost as if Hissom had known what Kate was going to wear to her big day and made sure she had an almost identical version.
She even wore a white headpiece similar to that worn by the newly titled Duchess of Cambridge, although Hissom's was unlikely to have been leant to her by the Queen.
While 1,500 guests - from heads of state and European royal families to lords and ladies - filled historic Westminster Abbey, Wynn's wedding was also spectacular.
Wynn, 69, invited a who's who of high rollers and celebrities to the $1 million
Hollywood-style ceremony held at his Encore resort in Las Vegas.

Donald Trump was among the 500 guests who arrived in Las Vegas earlier in the week for the three-day party. Wynn had told reporters actor and director Clint Eastwood would serve as his best man.
Before the event it was suggested that the wedding could become a $10 million money-spinner for the casino king as the big gamblers rub shoulders with guests like Donald Trump, actors Sylvester Stallone and Hugh Jackman and singers Celine Dion and Garth Brooks.

Wynn's wealthy friends include hotel magnate Sol Kerzner, financier Michael Milken and the investment Blackstone Group's Stephen Schwarzman.
The lavish arrangements prompted guests to dub it 'America's royal wedding.'
'Everybody is getting free rooms, making the cost of the wedding over $1 million. But it's good business,' a source told the New York Post last week.

Guests were flown in for a poolside 'white' party on Friday -- the same day William and Kate wed in London.
The following day, 1,000 guests attended the 'Grand Celebration' in the Encore Ballroom at 7.30 pm planned by High School Musical director Kenny Ortega.
A farewell brunch was then held on Sunday morning.
Wynn's ex-wife, Elaine, the mother of his two children, is reported to have left town and attending financier Warren Buffett's annual Berkshire Hathaway investors' seminar in Omaha.
Last year year she got one of the largest divorce settlements in history -- $741 million in stock in Wynn Resorts.
Wynn met Hissom, in her forties, on the French Riviera in 2008.
