Prince Harry and girlfriend Meghan Markle recently spent some time catching up with Queen Elizabeth II.

Last Thursday, the couple stopped by Buckingham Palace to sit down for tea with Queen Elizabeth, People reported. Prince Harry and the "Suits" star reportedly arrived at the palace in a Ford Galaxy station wagon with blacked-out windows. They were then "whisked up to the Queen's private sitting room" for the hour-long meeting.

According to Daily Mail, Prince Harry bringing his girlfriend to meet the queen is a big deal. He is currently fifth in the line of succession, but he will drop to sixth once Prince William and Kate Middleton's third child arrives. Thus, Prince Harry needs the monarch's permission to get married.

There are rumors suggesting that this was not the first time that Markle had met Queen Elizabeth II in person. The two important ladies in Prince Harry's life were believed to have first met during a visit to Balmoral Castle in Scotland.

In related news, an insider recently revealed what type of wedding Prince Harry may want to have with the "Horrible Bosses" star. The source speculated that the next royal wedding will not be as grand as Prince William and Middleton's 2011 ceremony.

"Pomp and pageantry is the last thing he would want," a source told Us Weekly. "I can see him wanting to get married at St George's Chapel at Windsor Castle. It would stop it from turning into a total media circus and give the day a sense of privacy that Harry so badly craves."

A number of royal experts are convinced that Markle's previous marriage is a major factor in the lavishness of their wedding. The "Dater's Handbook" star is a divorcee, and royals were previously prohibited from marrying people who have been divorced. Although this has changed over time, many believe that Prince Harry and Markle will have a low-key wedding similar to that of his dad, Prince Charles, and stepmother, Camilla Parker-Bowles.

"Meghan Markle has already been married, so I believe they would have a service of blessing," Hugo Vickers said.

"You wouldn't necessarily have a big grand ceremony, and it would be more like Charles and Camilla," Scott Peterson added.

Royal biographer Penny Junor also shared their opinion. "Meghan is, after all, a divorcee, so it would probably be a registry office ceremony with a church blessing afterwards," he told Town & Country (via Harper's Bazaar), before adding that it is unlikely for the queen to go to the registry office even for her grandson's wedding.
