Meghan Markle and Prince Harry secretly got married 3 days before their royal wedding

• Meghan Markle and Prince Harry had a secret backyard wedding three days before their royal wedding.
• They told the archbishop: "This spectacle is for the world, but we want our union between us."
• The revelation is one of many from the two-hour CBS primetime special with Oprah Winfrey.

Meghan Markle revealed in a tell-all interview with Oprah Winfrey that she and Prince Harry secretly got married three days before their televised royal wedding in 2018.

Over 29 million viewers tuned in to watch Markle and Harry's wedding ceremony at St. George's Chapel at Windsor Castle. But in the CBS interview, which aired Sunday, Markle said that they held a private ceremony as part of their desire to get " back down to basics."

"Three days before our wedding, we got married," she said. "No one knows that, but we called the archbishop and we just said, 'This thing, this spectacle is for the world, but we want our union between us.' So the vows that we have framed in our room are just the two of us in our backyard with the Archbishop of Canterbury."

"Just the three of us," Harry said, singing to the tune of Grover Washington Jr. and Bill Withers' 1980 hit "Just the Two of Us."

The revelation is one of many from the two-hour-long primetime special. Markle told Winfrey that Kate Middleton made her cry the week of her wedding over a flower girl dress and not the other way around, as had been reported in tabloids - and that members of the royal family had "concerns and conversations" about how dark Archie's skin would be before he was born.

The couple also announced that their second child, due this summer, will be a girl.
