The brunette turned heads in a very sexy chic red jumpsuit at the event thrown in honour of The Apprentice winner Dr Leah Totton on Tuesday night (18 February).
Love her look? Then good news! You can snap up her Paige Jumpsuit at Gorgeous Couture for £139, reduced from £179.
Jessica teamed her show-stopping scarlet outfit with simple black heels, an oversized gold clutch and a statement necklace.
She was also rocking her newly-bobbed hair after cutting her long locks at the start of the year. We have to say, we're loving her new look – and she seems to have kick-started a trend in Essex: Amy Childs and Gemma Collins have also gone for the shorter, chic look lately as well.
We're used to seeing Jess accompanied by long-time boyfriend Ricky Rayment, but last night she was enjoying an evening with close friend and TOWIE co-star Bobby Cole Norris at the Dr Leah Clinics Launch Party at Sheesh. (Dr Leah Totton won the last series of The Apprentice, securing the backing of Lord Alan Sugar to open an ethical, cosmetic clinic.)
It was a night away from filming the new series of TOWIE for Jess and Bobby.
Series eleven of the BAFTA-winning show kicks off on ITV2 on Sunday, 23 February at 10pm - and we can't wait to see how our favourite Essex stars are doing and meet some new faces.
