The songstress is usually seen wearing an array of bright coloured lipsticks and skin smoothing foundation, but on Tuesday night (10 September) she ditched her make-up bag and went au naturel, as she enjoyed an evening of pampering instead.
Posting a candid snap of herself taking a well earned break from her busy schedule, Jessie revealed to fans what her beauty routine consists of.
Alongside the no make-up snap she wrote: "Bath done. Hair mask on. Hydrate face mask done. Make up free and ready to throw down in the kitchen! #myarmlookslikeitisntmine #ilovebeingathome"
Well, that hydrating face mask seems to have worked wonders because her skin is glowing!
And although Jessie, 25, may have shaved her long locks off earlier this year, she is still sticking to the habit of keeping her hair well conditioned with a moisture-rich mask. Could she be preparing to grow her style out a little?
The pop star - who was recently nominated for a MOBO Award - is currently gearing up for the release of her second studio album, Alive, on 23 September and has been filling her diary with various gigs and festival performances.
But despite all of her travelling and red carpet appearances, she is clearly a homebird at heart and prefers to unwind like the rest of us - with some chocolate!
She also uploaded a picture of her munching on a Time Out yesterday and wrote: "Only my 3rd one... #timeouts #ijustlovethem"
