Meghan Markle's estranged father, Thomas Markle, says her interview on 'The Ellen DeGeneres Show' was embarrassing for the royal family

• Thomas Markle says Meghan's appearance on "The Ellen Show" was embarrassing for the royals.
• During her appearance, Meghan took part in a number of prerecorded pranks.

The Duchess of Sussex's estranged father, Thomas Markle, criticized her appearance on "The Ellen DeGeneres Show."

During Meghan Markle's appearance on the daytime talk show on Thursday, she discussed her new life in California with Prince Harry and her children's book, "The Bench."

She also took part in a number of pranks in a recorded segment of the show. DeGeneres gave Markle orders through an earpiece, including to eat "like a chipmunk" and to say she had healing powers.

"It's no way to behave. The whole thing was kind of embarrassing. It was certainly embarrassing for the royal family," Thomas Markle told The Sunday Mirror. "It's embarrassing for her as well. I suspect it embarrassed everyone in the UK, too.

"She's putting herself out there as a duchess but I've never seen a duchess behave this way, doing stupid stunts," he added.

During the interview, Markle recalled the car she used to get to her acting auditions, a Ford Explorer, and said she had to climb in through the trunk because the key had stopped working on the driver's car door.

"The Ford Explorer she had in her early 20s that she mentioned was a good running vehicle. I don't remember any time she had to crawl out of the back of it to get out, like she said," Thomas Markle told The Sunday Mirror.

"The doors worked fine on that vehicle until the day she got rid of it," he added.

Representatives for the Duchess of Sussex did not immediately respond to Insider's request for comment.
