One paper, for example, published a photo of Harry with the caption "Game of Moans: Harry's Megxit PS5 title launch for coronation."
Another paper went with an edited photo of Prince Harry and Meghan Markle with the caption "Call of Dukey."
On Thursday, Harry returned to the High Court in London where his lawyer is fighting an attempt by a newspaper publisher to throw out his and other high-profile figures' lawsuit.
The lawsuit alleges widespread unlawful acts by journalists, including phone-hacking and other serious privacy breaches by journalists from the Daily Mail and Mail on Sunday or private investigators working on their behalf.
Along with singer Elton John and five other high-profile people, Harry is suing publisher Associated Newspapers.
Associated Newspapers is seeking to have the lawsuit thrown out before a trial, arguing that the claims, some dating back 30 years, were outside a six-year time limit for legal action. The publisher's lawyer, Adrian Beltrami, told the court on Wednesday that the claims were rejected "in their entirety."
David Sherborne, the lawyer for Harry and the other claimants, explained why they had not sued before. He said they had been put "off the scent" by unequivocal denials made at a 2011 public inquiry by top executives from Associated.
Prince Harry has now returned to the United States after attending the court hearing.
