The 58-year-old braved the freezing cold temperatures to put on an eye-popping display in the all black ensemble.

Nutritionalist Gillian let her body do the talking as she squeezed her petite frame into some skintight cycling shorts. 

She teamed the thigh-high hot pants with a barely-there lace top, which fell to her ankles. 

Not one to miss an opportunity, Gillian proudly pulled apart her lace number to ensure that her toned legs were on full display. 

She finished the look with an Amy Winehouse style beehive and chunky black heeled boots. 

The former I'm A Celebrity… Get Me Out Of Here! star was accompanied by her 17-year-old daughter Afton who matched her mother with a similar outfit. 

She was later spotted cuddling up to former EastEnders' actress Daniella Westbrook as the party was in full swing.

Gillian is certainly used to flashing the flesh of late as fans of the You Are What You Eat star will recall her equally daring Halloween outfit. 

The blonde donned a black leotard which she covered up with a cobwebbed coat. 

Once again, she pulled the garment apart in order to reveal her physique in what appears to be her trademark pose.
