Prince Harry and Duchess Meghan seem to have a new distraction on their hands.

You might recall that Meghan's half-brother Thomas Markle Jr. is becoming a reality star on Big Brother VIP. The show hasn't premiered yet, but Markle is already trying to start drama with Meghan and Harry in a weird preview released today.

Meghan Markle's half-brother Thomas on Big Brother VIP

Markle's claim to fame on the "celebrity" show appears solely to be that he's the brother of the Duchess of Sussex.

With the title "Meghan's Big Brother," he introduces himself in the preview seen below: "I'm Meghan Markle's brother. She's very shallow," he says (around the 0:55 mark).

Markle goes on to reference a time he wrote to Prince Harry telling him not to marry his half-sister. "You know I'm famous for writing letters," he claims.

"I'm gonna write a letter to Meghan," he adds, apparently doing so in an episode of the new series. "Dear Meghan and Harry: The first thing I wanna say to both of you..." Markle reads, before the clip cuts.

Thomas Markle Jr. and his sister Meghan

Thomas Markle Jr. is one of a few semi-notable names starring in Australia's upcoming Big Brother VIP, which doesn't appear to have a start date just yet.

He's joined by reality star and athlete Caitlyn Jenner along with former reality star and Trump aide Omarosa, to name just a few co-stars.

As half-siblings, Thomas and Meghan share the same father, Thomas Markle Sr. The Duchess of Sussex is known to have a complicated relationship with her father and two half-siblings — Samantha and Thomas Jr.

Meghan's half-brother Thomas Markle Jr. will star in Big Brother VIP.

Apart from being Meghan's brother, Thomas has worked as a window fitter and celebrity boxer, and he's had a few brushes with the law.

Meghan is largely estranged from her father and half-siblings, but they pop up in the media from time to time, typically using her name to bring attention to themselves.

Such was the case when Thomas Markle Sr. threatened to take his daughter to court so he can see his grandchildren Archie and Lilibet this summer.
