There were monarchs, presidents, prime ministers — and David Beckham. Yesterday’s opening ceremony for the London Olympics was an A-list affair.

Among the 60,000 spectators at Olympic Stadium was Queen Elizabeth II — who as British head of state officially opened the games — along with royals including Prince William and his wife Kate, and Prince Harry.

There was a sprinkling of showbiz royalty, too, with Brad Pitt and Angelina Jolie, recently filming in Britain, the most often-cited names.

The British government said more than 80 heads of state and government will be in the audience, including royalty from Brunei, Luxembourg, the Netherlands, Spain and Sweden.

The US was represented by first lady Michelle Obama and Republican presidential hopeful Mitt Romney also attended.

Beckham, who helped bring the games to London and is widely rumored to have a role in the ceremony, was also there, and British newspapers have speculated that boxing great Muhammad Ali may also be involved.

The show, a £27 million spectacular titled “Isles of Wonder,” ended with a performance by Paul McCartney.
