Fast-forward seven days and she finds herself one of the most photographed women in the world as the new squeeze of Britain's remaining royal bachelor Prince Harry.
Fortunately for the massed ranks of the world's media the 25-year-old beauty is a lingerie and swimwear model by trade and has a back catalogue of sizzling pictures to make even the most seasoned of tabloid editors weep.
And as the week has gone on ever more sexy snaps have emerged!
Ms Brudenell-Bruce – a descendant of the seventh Earl of Cardigan, who led the Charge of the Light Brigade - is no dummy.
She was privately educated at the high-class Stowe School in Buckinghamshire before going on to study history of art at Bristol University - the same degree subject as Prince William and his wife Kate Middleton.
She has starred in a Bollywood movie and is an avid collector of fine art with a portfolio worth millions.
But she was smart enough to realise she could turn her good looks and gorgeous figure into cash by modelling swimwear and lingerie.
And she has stripped off (and slipped on) for big name brands like John Lewis, Knickerbox and Adidas.
And she uses the cash to fund her love of fine art.
She said: “Modelling and acting are what I do but they can be such a rollercoaster, whereas art is lovely to have in my life as a constant.
“I am obsessed with it. Whenever I finish a shoot, I come home with another piece under my arm.”
