LOS ANGELES (AP) ― Wills and Kate were just the warm up for the true wedding of the century.

After years of cohabitation, six kids and countless tabloid headlines, Brad Pitt and Angelina Jolie made it official: They plan to make it official.

If you thought the media circus involving the world’s most glamorous couple was on overdrive before, just wait. Now that Brangelina are officially engaged, expect endless speculation about where and when they’ll wed, what they’ll wear, what their kids’ roles will be, and who might get to attend the celebration.

“This is really a state wedding,’’ said Stephen Galloway, executive editor of features at The Hollywood Reporter. “This is America’s equivalent to Prince William and Kate Middleton.’’

He called the Brangelina wedding “the media event of the new century.’’

Pitt’s manager confirmed the couple’s engagement Friday after Jolie was spotted wearing a diamond ring on her wedding finger. Jeweler Robert Procop said he spent a year working with Pitt to design the ring.

“The prominent engagement ring is giving the world a warning,’’ Galloway said. “It says ‘look out, get ready.’’’

But Bradley Jacobs, a senior editor at Us Weekly, sees things differently. He anticipates the wedding will be a private, even low-key affair. “I don’t think you’re going to see a bunch of fanfare,’’ he said. “It’s certainly not going to be a Kim Kardashian-style wedding ... It’s going to be very subdued.’’

Still, expect massive media coverage either way: “We will not rest until we know when and where and how and who’s going to be there,’’ Jacobs said.

Entire magazine issues could be devoted to each star’s wedding-day outfits and hairdos.

“Every single designer on the planet will be pursuing Angelina for the dress,’’ Galloway said. “It’s literally worth millions of dollars in business.’’

Jolie’s wedding dress is a career-making outfit for the winning designer.

Even Pitt’s look leaves room for ample speculation: Long hair or short? Facial scruff or clean shaven? A classic tuxedo? And designed by whom?
