The ex Suits star went on to urge people to “report” any information they believe is wrong and to stop “contributing to or even clicking on misinformation”.
Piers shared an article about Meghan’s interview on Twitter, in view of his 7.6 million followers.
Appearing to mock her comments, he simply captioned his post with a series of crying with laughter emojis.
The ITV star previously said the pair had exchanged friendly messages on Twitter before she met Prince Harry.
He told The Mirror: “I was friendly with Meghan but she ghosted me. I am not impressed.”
