About Her

Shoots, Costumes and Two Home Cities

Alexandra Marianna has been on X since 2019 and on TikTok since 2020, but most of her work lives on Instagram: styled photo shoots, short reels and the occasional mirror selfie from a salon chair.

Costumes are a running thread. She has posted as Sharon Tate at a Tarantino-themed Halloween party in London, as a blonde Princess Leia and as Harley Quinn, and she calls a 2025 Star Wars desert shoot one of her favourites.

She splits her time between Los Angeles and London, and her feed follows her: St Lucia, Cape Town, Bali and Japan have all turned up in the last few years. Her bio on both Instagram and X reads, simply, “half human”.

Not Every Alexandra Marianna Online Is Me

On Instagram there are copies of my name with a dot or a number added: @alexandra.marianna, @alexandramarianna1 and @alexandramarianna2. There is a YouTube channel under my name that I don't run. And @alexmarianna on Instagram is a different person altogether, even though alexmarianna is my handle on TikTok and Link.me.

This website is the only source I control. If an account isn't listed on my official links page, it is not me — no matter whose face is on it.

Same Name, Different People

Instagram copies with a dot or a number, a YouTube channel under my name, a real person who owns @alexmarianna on Instagram, and an actress in Brazil. None of them are me.
