If you had Googled 'Jessica Mulroney' last week, you would have found many articles about the fashion expert who styles a Canadian first lady and is best friends with royalty.

Now, the 40-year-old is in the news for a far more serious reason.

This week, Mulroney stepped back from her social media platform and has been dropped by a number of networks and brands after Canadian blogger and influencer, Sasha Exeter, shared that she had been subject to "a series of very problematic behaviours" from the TV star and stylist.

Here is everything you need to know about this evolving story.

Who is Jessica Mulroney?

Mulroney is also a close friend of Meghan, Duchess of Sussex, who she met while styling Sophie Grégoire Trudeau, former TV host and wife of Canadian prime minister Justin Trudeau.

Mulroney is married to Ben Mulroney, the son of former Canadian Prime Minister Brian Mulroney.

Why is Jessica Mulroney in the news?

On June 11, Canadian blogger and influencer, Sasha Exeter, posted an IGTV video titled 'My Amy Cooper Experience' on Instagram.

In the 12-minute video, Exeter detailed how Mulroney, a former acquaintance, contacted her after she posted a general callout on her Instagram about the importance of high-profile figures, including herself, using their platforms to support the Black Lives Matter movement and the global protests sparked by the death of George Floyd.

According to Exeter, the private exchange between herself and Mulroney took place on June 3 and began because Mulroney assumed the callout was directed towards her.

"What happened next was a series of very problematic behaviours and antics that ultimately resulted in [Mulroney] sending me a threat in writing," Exeter said.

"[The messages] ended in her saying, 'I have also spoken to companies and people about the way you treated me unfairly. You think your voice matters. Well it only matters if you express it with kindness and without shaming people who are simply trying to learn. Good luck.'

"I am by no means calling Jess a racist. But what I will say is this: she is very well aware of her wealth and her perceived power and privilege because of the colour of her skin. And that, my friends, gave her the momentary confidence to come for my livelihood, in writing."

Exeter went on to compare Mulroney's behaviour to that of Amy Cooper, the white woman who threatened a black man, Christian Cooper, in May by calling the police on him while both were walking through the Ramble in New York City’s Central Park.

"Not only is Jessica very well aware of her white privilege, but just like…Amy Cooper, she spewed out that threat so effortlessly. But I think what makes the situation really horrendous is the threat or the claim that she was going ahead and speaking to brands and companies that I potentially have worked with or am currently working with or could possibly work with.

"That’s a threat to my livelihood. For her to threaten me, a single mum, a single Black mum, during a racial pandemic, blows my mind. It is absolutely unbelievable."
