AceShowbiz - Lawyers for Prince Harry and Meghan Markle, Duchess of Sussex have threatened to sue British media bosses over the publication of photos featuring the new mum and their baby boy in a public park in Canada.

The former "Suits" actress has been lying low on Vancouver Island with the couple's son, Archie, ever since it was announced that she and Harry would be stepping down as senior members of the U.K.'s royal family in a bid to live a more private and financially independent life away from the spotlight.

The Duke and Duchess plan to split their time between Britain and Canada, but life in North America has already had a rocky start as their lawyers fired off cease and desist notices to editors at various U.K. outlets on Tuesday, January 21, warning them against purchasing or publishing images of a smiling Meghan hiking with two dogs, with Archie strapped to her chest in a baby carrier.

According to TMZ, the legal letter reads, "There are serious safety concerns about how the paparazzi are driving and the risk to life they pose" - an apparent reference to the tragic death of Harry's mother, Diana, Princess of Wales, who was killed in a 1997 car crash in Paris, France after a high-speed paparazzi chase.

However, the pictures had already surfaced online on Monday, and featured on the front page of The Sun on Tuesday, suggesting court action is imminent.

The couple, which wed in 2018, is no stranger to taking members of the press to court - Harry and Meghan are currently locked in a British legal battle with officials at The Mail on Sunday and its parent company, Associated Newspapers, after the "unlawful" publication of a private letter the Duchess had written to her father, Thomas Markle.

Meanwhile, Harry has filed papers against the owners of The Sun, the defunct News of the World, and the Daily Mirror, in relation to allegations of phone-hacking.
