According to Meghan Markle's half-brother, Thomas Markle Jr., Meghan Markle is exaggerating her mental health issues. 

The 55-year-old lambasted the Duchess of Sussex in front of his housemates during an episode of "Big Brother VIP."

As the others looked on, he informed Fitzy and Wippa that he doesn't "100% buy" Meghan's claims that she faced mental health concerns while living in the UK as a member of the British royal family.

"I don't 100% buy that." 

Thomas' response to the Duchess' disclosure during her famous Oprah interview caused gasps from his fellow housemates when he was asked about it. 

"That was horrible," one of the housemates, Bernard, shouted when the interview ended.
