Royals watch:

Prince Albert and Charlene Wittstock kicked off their three-day wedding celebration Thursday night at a public concert with the Eagles — yeah, go figure — and 15,000 fans. They’ll marry in a civil ceremony Friday in the palace throne room, followed by a religious ceremony Saturday in the palace courtyard with 3,500 guests including designers Karl Lagerfeld and Giorgio Armani (who designed the wedding gown), soprano Renee Fleming and Olympian gymnast Nadia Comaneci. It’s Monaco’s first wedding of a reigning prince since Albert’s parents, Prince Rainier and Grace Kelly, married in 1956.

• Meanwhile, Prince William and bride Catherine began their first official tour as a married couple when they landed in Ottawa Thursday. The newlyweds will celebrate Canada Day — the national independence day — Friday (on what would have been Princess Diana’s 50th birthday) and spend nine days in the country before heading to California on July 8.
