Meghan Markle is reportedly very upset that Jessica Mulroney brought her up in a "discourse" she had with lifestyle writer Sasha Exeter (opens in new tab), and apparently that was the last straw for their friendship.

Recall that Sasha only recently asked fellow fashion industry influencers (including Jessica) to use their platforms to support the "Black Lives" movement (opens in new tab), whereas Jessica essentially used "textbook white privilege" to threatened her career, she told her followers (opens in new tab). Jessica seemed to bring up Meghan Markle in response, writing in Sasha's post (opens in a new tab), "I'm so glad you're not a white girl. I learned a lot."

Page Six previously reported that Meghan was cutting ties with Jessica (opens in new tab), and now sources at Us Weekly (opens in new tab) say that the Duchess is particularly upset that Jessica brought her up.

"Meghan was not happy that Jessica brought up her relationship with Meghan when she commented on her "closest friend" in her discourse with Sasha," a source tells Us. 'It was very offensive to Megan and it was a defining moment. Meghan believes the relationship is over."

Another source explained that Meghan wants to "distance herself" from Jessica, "Of course Meghan is supportive of Jessica, as she is with all of Jessica's friends, but it is a little uncomfortable that Jessica seems to be using their friendship for headlines." She added. Especially now that Megan is in LA and at an impressionable time, Megan is very cautious about her friendships"

Jessica's TV show "I Do, Redo" was cancelled (opens in new tab) due to her treatment of Sasha, and she will no longer appear on "Good Morning America." She later issued an apology for her comments to Sasha.
