I believe she was escorting at a high level. She came from Sweden, where she was a beauty queen, which is why they connected I guess. Common language or background. However, I don't think they speak anymore. For two reasons I'd guess: Mimie saw Anna was a snake / Anna decided Mimie was doing better and was jealous of her. Mimie seems smarter than Anna overall. She's putting out her own line of swimwear now, she previously had a short lived clothing line called Mimi London doing Chanel tweed knockoffs at a good price.
What I find odd is that she used to wear an engagement ring, even though I've heard she was always with a married man, not a man of her own. She has a legit career in cooking, and online you can even find her interview when she worked at Chelsea football club as a chef. You can even see her old Myspace page lol. Unlike Anna she'll be fine I'm sure. She is private and keeps to herself.
