Kelly Slater drags Princess Diana into explosive swipe at royal family

Surfing legend Kelly Slater has taken an astonishing swipe at the royal family in the wake of Prince Harry and Meghan Markle's tell-all interview with Oprah.

The 49-year-old Slater joined the chorus of celebrities weighing into the drama after some explosive allegations made by the Duke and Duchess of Sussex.

But Slater took things to disturbing levels on Wednesday when he dragged Princess Diana and her former lover James Hewitt into the furore.

In explosive social media comments, the 11-time surfing world champion wrote: “Id be mad too if I was James Hewitt’s unacknowledged, illegitimate kid, got essentially kidnapped and held hostage by the royal family, was forced to pretend that boring, square Prince Charles was my dad all those years, then they cut off my trust fund, and disapproved of my hot, American wife cause it didn’t fit into their ongoing inbreeding program.

“Did I miss anything?”

Diana had a much-publicised affair with former military officer Hewitt in the mid-90s.

Almost 30 years on, rumours still abound that Hewitt is Harry's biological father, not Prince Charles.

Royal experts have previously discredited the theory, pointing to the fact that Harry was born before the affair is believed to have occurred.

Serena Williams shows support for Meghan Markle

Slater isn't the only iconic athlete to weigh in on the furore, with Serena Williams throwing her support behind friend Markle.

Reacting to the interview on social media, Serena also took aim at the media and "tabloid journalism."

“Meghan Markle, my selfless friend, lives her life – and leads by example – with empathy and compassion,” the 23-time grand slam champion tweeted.

“She teaches me every day what it means to be truly noble. Her words illustrate the pain and cruelty she’s experienced.

“I know first hand the sexism and racism institutions and the media use to vilify women and people of colour to minimise us, to break us down and demonise us.

“We must recognise our obligation to decry malicious, unfounded gossip and tabloid journalism.

"The mental health consequences of systemic oppression and victimisation are devastating, isolating and all too often lethal.

“I want Meghan’s daughter, my daughter and your daughter to live in a society that is driven by respect.

“Keep in your memory the fruitage of the spirit is love, joy, peace, long-suffering, kindness, goodness, faith, mildness, self-control. Against such things there is no law.”

Markle has attended a number of Serena's matches throughout her career, while the tennis legend was also invited to Harry and Meghan's wedding.
