Meghan's first marriage lasted just two years. Mr Engelson has since remarried after announcing his engagement weeks after Meghan and Harry were wed.

And in a new trailer for Australia's Big Brother VIP, Thomas claimed Harry's "on the chopping block next".

Meghan is not close with Thomas and it's not known if he has any knowledge of the circumstances behind her split from Mr Engleson.

However, in the trailer, he said: "The guy that she was married to the first time - she just walked all over him and dumped him."

In response to another housemate who says that sounds "cold-blooded", he nodded before adding: "Harry's on the chopping block next."

Meghan married Mr Engelson, 44, in September 2011.

They split just 23 months later, in August 2013, citing irreconcilable differences.

The duchess is likely bracing for fresh embarrassment as Big Brother continues.

Thomas was also shown in the diary room preparing to write a letter to the Sussexes.

He says out loud: "Dear Meghan and Harry, the first thing I want to say to both of you..."

The trailer then abruptly ends.

FRESH EMBARRASSMENT

Thomas has made a number of comments about his sister and her marriage since it was announced that he'd be joining Big Brother.

In August, he claimed he'd warned Harry that "very shallow" Meghan would "ruin" his life.

As he arrived in a limo, he told cameras: "I told Prince Harry, I think she's going to ruin your life."

He claims he's "not bitter - just baffled".

"It's hurtful given how close we once were," he said.

Thomas Markle Jr

"I’m confused and a little distraught because here is a person knowing the position she’s in and knowing the scrutiny she’s under and yet she has forgotten her flesh and blood."

Before Harry and Meghan's wedding, Thomas sent the groom a letter saying it wasn't "too late" for him to back out as his sister was "obviously not the right woman for you".

He claims the last time he saw Meghan was a decade ago in 2011.
