Prince Andrew Uses Banned 'His Royal Highness' Title In Now-Deleted Instagram Post On Ex-Wife Sarah Ferguson's Account

A royal mistake!

Prince Andrew, 62, apparently used his banned "His Royal Highness" title in an Instagram message on his ex-wife's page before deleting the entire post just hours later.

According to People, the Duke of York — who was stripped of his royal titles amid his sexual assault lawsuit earlier this year — shared a post to Instagram via his ex-wife Sarah Ferguson's account to reflect on the 40-year milestone of him leaving to serve in the Falkland War with the Royal Navy.

The post on Ferguson's page concluded with the message: "written by HRH The Duke of York," before it was later adjusted to remove the His Royal Highness title since he was banned from using the phrase in any official capacity.

After the HRH title was removed, the post didn't stay up for long and was reportedly deleted entirely just hours later.

Queen Elizabeth II stripped Andrew of his military titles and royal patronages in January after he was named in a lawsuit filed by Virginia Giuffre, who claimed she was forced to have sex with the royal when she was only 16 years old.

Andrew later settled the suit outside of court, paying his accuser an estimated $16 million to put the matter to rest.

Despite the lingering controversy surrounding his past, Andrew has been slowly making his way back into royal life, as he recently made an appearance at Prince Philip's memorial service last month.

While Andrew was in attendance to escort his ailing mother, the Queen, into the Thanksgiving ceremony, many were still surprised to see him showing his face at such a public event since being wrapped up in the lawsuit scandal.

Andrew — who is rumored to have been associated with convicted pedophile Jeffrey Epstein — has been spending more time with Her Majesty amid her recent health woes, with insiders insisting he's using "his closeness to the Queen as a springboard back into pubic life," as OK! learned.

Senior royals Prince William and Kate Middleton are even planning to move to Windsor amid fears that the Queen is growing too close to Andrew, who lives just next door to the monarch.
