Prince Harry and Meghan Markle are facing family controversy just days before their wedding, but they are not the first royal couple to do so.

Markle, 36, is dealing with her father, Thomas Markle Sr., potentially not attending her wedding this Saturday after he was accused of taking part in staged paparazzi photos.

Markle Sr. allegedly told TMZ he no longer plans to walk his daughter down the aisle in front of an expected 600 guests at St. George’s Chapel. He also reportedly told TMZ he recently suffered a heart attack and now has chest pains.

"Not only is [Markle] upset about the fact that that’s not going to happen," ABC News’ royal contributor Victoria Murphy said of Markle Sr. attending the wedding, "but she’s obviously very worried about him and what is going on.”

Harry said in his first interview with Markle after their engagement was announced last November that they’ll get through anything together “as a team.”

“Whatever we have to tackle together or individually, it will always be us together as a team, so I think she's capable,” Harry said of Markle, who responded by saying, “That’s so nicely said, isn’t it?”

Just before the wedding of Harry’s parents, Prince Charles and the late Princess Diana, in 1981, there were reports about whether Diana’s father, who had suffered a stroke a few years prior, would be able to walk her down the aisle.

Though shaky and clinging to Diana’s arm, John Spencer, then 78, was able to make the slow march to the altar at London’s St. Paul's Cathedral.

Watching from a pew at Diana and Charles’ wedding was Camilla Parker Bowles, who would later go on to marry Charles and become Camilla, the Duchess of Cornwall.

Friends of Diana later said that she tried to block Camilla from even being invited to the wedding.

Three decades later, Charles and Diana’s older son, Prince William, watched as Kate Middleton’s family faced scrutiny before their 2011 wedding.

The Middletons were plagued by rumors swirling over Kate’s uncle, Gary Goldsmith.

“When Kate married William, her family was hugely under the spotlight as well and there were members of her family, her uncle for example, who were doing things that were making big stories in the media, that were causing a lot of controversy for the royal family,” said Murphy.
