Prince Charles reportedly doesn’t approve of Sarah Ferguson amid rumors that she’s back with his younger brother, Prince Andrew.

The Duke and Duchess of York have been divorced for over a decade, but they have maintained their friendship and close bond. In fact, they still live together in Royal Lodge and have been seen attending royal engagements together, sparking rumors that they may have reconciled after Fergie's cheating scandal.

An insider told The Sun’s Dan Wootton that Prince Andrew and Ferguson aren’t seeing anyone else at the moment. The source added “officially they’re very good friends with benefits.”

The palace hasn’t confirmed the real status of Prince Andrew and Ferguson’s relationship. However, even if they do give their relationship another try, Prince Charles might not support their second chance at love.

According to an insider, Prince Charles is “not OK with Fergie,” before adding that the Prince of Wales can’t stand the duchess. The source continued by saying that Prince William and Prince Harry’s father thought Ferguson brought embarrassment to the royal family in the past, leaving his relationship with his brother “strained.”

In addition, Prince Charles and Ferguson reportedly don’t get on personally. There’s so much baggage between the two, especially since the future king felt that Ferguson sided with Princess Diana over his second wife, Camilla Parker-Bowles, years ago.

In addition, there were fears that Ferguson would never stop promoting herself and looking for ways to make money off her royal position.

Prince Charles’ opposition of Ferguson and Prince Andrew’s romance seems to be given. In Netflix’s documentary “The Royal House of Windsor,” royal expert Katie Nicholl shared a glimpse of Prince Charles' relationship with Prince Andrew and how the heir deemed his younger brother a liability. She also touched on how his relationship with Ferguson “riles” the Prince of Wales.

“[Prince Andrew's] relationship with [Sarah Ferguson] is one of the things, I’m told, that really riles Charles. It all contributes together into something that is just not very palatable,” Nicholl said.

But while Prince Charles doesn’t approve of Prince Andrew and Ferguson’s reunion, Prince Philip reportedly doesn’t care anymore on any level. The Duke of Edinburgh initially didn’t like Ferguson for Prince Andrew too.

The Duke and Duchess of York weren’t affectionate during Princess Eugenie’s royal wedding, and sources said that they kept their distance because they didn’t want to annoy the 97-year-old royal who was sitting behind them.
