Prince Harry and Meghan Markle's wedding will likely be modest.

Although Prince Harry and Markle have yet to announce or even hint at their engagement, rumors have been claiming for months that the duke has already popped the big question and will announce it soon. Some royal experts have also speculated on their wedding, especially where, when and how it will happen. According to a new insider, the couple's wedding will likely be private and will not be extravagant.

"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."

The source also claimed that Prince Harry's family is very supportive of their relationship. When asked if Queen Elizabeth II will attend the ceremony, the insider said, "Of course. No question."

However, according to some royal experts, Prince Harry and Markle might have a civil wedding ceremony if they do end up tying the knot. The "Suits" star was previously married to Trevor Engelsen, and royals were initially forbidden from marrying divorcees. Although this rule has already changed, some are expecting Prince Harry to follow his father's footsteps and have a low-key civil wedding ceremony instead of a lavish one like Prince William and Kate Middleton.

"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.

However, if Prince Harry and Markle will end up choosing to have a civil wedding in a registry, the queen may not attend. "Meghan is, after all, a divorcee, so it would probably be a registry office ceremony with a church blessing afterwards," royal biographer Penny Junor told Town & Country (via Harper's Bazaar). "If it was to be in the UK, then I would guess that all senior members of the royal family would be there, but I don’t think the Queen would go to the registry office."

In related news, a source claimed that Markle has already decided to quit USA Network's "Suits." The actress is expected to wrap up filming her last season soon and fly back to London in November.
