Chrissy Teigen has been a devoted ally to Meghan Markle amidst her and Harry's controversial departure from their royal duties and moving to the U.S.

Prior to Markle's tell-all interview with Oprah Winfrey over the weekend, Teigen shared a warning to critics of the Duchess of Sussex.

"This meghan markle sh*t is hitting too close to home for me," said Teigen, who became concerned for Markle's health.

"These people won't stop until she miscarries. f'king stop it."

Both women—who met as models on the game show Deal Or No Deal in 2007—have experienced pregnancy loss.

Markle revealed in a moving New York Times essay she suffered a miscarriage in July 2020.

The child would have been a sibling to her and Harry's firstborn, Archie.

"Losing a child means carrying an almost unbearable grief, experienced by many but talked about by few," she wrote in her roughly 1,000-word essay.

"In the pain of our loss, my husband and I discovered that in a room of 100 women, 10 to 20 of them will have suffered from miscarriage."

"Yet despite the staggering commonality of this pain, the conversation remains taboo, riddled with (unwarranted) shame, and perpetuating a cycle of solitary mourning."

The grief was all-too-familiar for Teigen, who herself suffered a pregnancy loss late last September.

The supermodel and cookbook author opened up about the loss of her and her husband John Legend's unborn son they named "Jack" in an emotional essay on Medium—where she described the experience as "utter and complete sadness."

Teigen—who had previously been diagnosed with partial placenta abruption—revisited her painful memory last month on Instagram when Jack's due date was expected to have been.

She wrote:

"He would have been here any day now - if he were like Luna and Miles [her other children], I'd probably be holding him as we speak."

"I am so full of regret that I didn't look at his face when he was born. I was so scared of seeing him in my nightmares that I forgot about seeing him in my dreams. I hurt every day from that remorse."

"This month is a rough reminder and to be honest, I thought the worst was over but I guess life and emotions aren't on any sort of schedule."

Twitter backed Teigen's concern for Markle and they admonished the persistent harassment of the Duke and Duchess of Sussex by the royals and the media.

The Duke and Duchess of Sussex are expecting their second child later this year.
