But at £240 a pop, we fear we're never going to get our hands on the Made In Chelsea star's latest lust-worthy scent – sigh...
Rosie took to Instagram on Monday (4 April) to reveal some of her "Monday essentials" – a far-cry, is has to be said, from our Monday morning essentials of strong coffee, a bowl of cornflakes and a pair of battered Converse!
For Rosie, it was all about her gold Gucci loafers, Rosie Fortescue Jewellery and her newest beauty obsession...
"My new favourite @jomalonelondon scent, Oolong Tea from their new Rare Teas collection," she posted along with the snap, above.
Jo Malone is well-known in the fragrance world for such cult, celebrity favourites like Red Roses; Lime, Basil & Mandarin and Pomegranate Noir. And this spring sees the launch of her Rare Teas Collection which consists of six refined scents to tantalise those tea tastebuds.
The collection hasn't even launched yet (it's due out at some point this month), but Rosie clearly managed to get her hands on one of the fragrances already. And yes, we're just a little bit jealous.
Oolong Tea is a woody little number, concocted from tea from the mountains of China, blended with bitter cacao, hay, tobacco leaves and tonic bean.
Sounds all rather fancy? That's because it is – and the price tag (£240 each) says it all, gulp!
Tea is having a bit of a moment in fragrances right now, but if you're not convinced you can spare a couple of hundred quid for Rosie's favourite tea-inspired scent, there are plenty more to try...
We love L'Occitane Thé Vert & Bigarade, £52, debenhams.com which contains green tea extract and bitter orange for a clean, cologne-esque type of scent you can even share with you man (if you're kind enough, that is – we're not!).
Annick Goutal L'Île au Thé, £67, johnlewis.com is another zesty goodie which combines tea leaves with mandarin, apricot and white musks.
And finally, there's Elizabeth Arden Green Tea Eau De Parfum Spray, £22, boots.com which is like a refreshing iced tea on a summer's day, with notes of peppermint, fennel and celery spice.
