Prince Harry unexpectedly arrived at the High Court in London to argue his case against the publishers of the Daily Mail.

Yes, there have been many trials involving the Sussex couple and Associated Newspapers.

In October, the Duke of Sussex, along with Sir Elton John, David Furnish, Sadie Frost, Elizabeth Hurley, and campaigner Doreen Lawrence, announced legal action against the Associated Press for "abhorrent criminal conduct and gross invasion of privacy" .

They are suing over a series of accusations, including allegations of using phone tapping to listen in on sensitive information.

The publishers call the allegations "baseless and highly defamatory claims that are not based on credible evidence," but the duke was photographed in London on Monday looking quite confident.

One Sussex fan tweeted the photo with the caption "That feeling when you're about to take down the daily mail."

Omid Scobie, a royal reporter and Sussex biographer, tweeted that "as the Duke of Sussex himself has said, it has been his 'life's work' to bring positive change to the British media landscape." [Author and royal commentator Dr. Shola Moss-Shogbamim said, "Prince Harry is here and serious about crushing the Daily Mail with phone hacking. We love to watch it."
