Meghan Markle's half-brother gave the duchess a menacing warning in a new promotional video.
Channel 7's Taylor Auerbach shared an exclusive clip from his interview with Meghan's family - including her father and estranged half-siblings.
Taking to Twitter to share the promotional clip, Taylor wrote: " WORLD EXCLUSIVE: This Sunday on @7NewsSpotlight Meghan Markle as you’ve never seen her before.
"For the first time, the Markles unite with an extraordinary message on the eve King Charles III’s coronation. These hidden tapes will stun the world! Only on @Channel7."
In the video, Samantha Markle claimed : "She would still be a waitress if it wasn't for dad."
Meghan's half-brother Thomas Markle Jr warned her: "We're not going to go away. This is going to change everything."
Another showed Samantha saying: "They're really unhealthy for each other, it's a toxic relationship," over a video of Meghan and Harry united and holding hands.
Towards the end of the video, they teased a "bombshell" about Prince Andrew as the voiceover artist said: "Is this the biggest Prince Andrew bombshell yet?"
It then cut to a clip of a mystery woman sitting in a room as the interviewer asked: "What is your relationship with Prince Andrew?"
Meanwhile, Thomas Markle took a different tone to his children and made a "deathbed plea" to "the daughter he lost."
"How can I fix this?" he says breathlessly. Thomas suffered from a stroke last year and confessed that he was "lucky to be alive."
At the time, a source told The Mirror that Meghan was concerned for her father, despite being estranged from her family.
"Despite their estrangement, Meghan is concerned," the source revealed. "She wants to know if there is any way to contact her father privately, without other family knowing about it or having to get involved."
Thomas' plea comes after it was revealed that Meghan would not be joining Harry for King Charles' Coronation later this month. Instead she is set to stay at their family home in California with their children Prince Archie and Princess Lillibet.
