Hardly surprising, as both weigh in at 8st and, save for a couple of inches in height (at 5ft 6in, Jane is two inches taller) and different eye colours (Jane's are brown, Janet's are blue) they are virtually identical. 

But Janet and Jane are not twins. They aren't even sisters. They are mother and daughter. And, in what many will see as a depressing indictment of today's youth-obsessed society, Janet confesses to having spent more than £10,000 on plastic surgery in a desperate effort to bridge the 22-year age gap between herself and her daughter.

In this image-conscious age, it is a bittersweet moment for many mothers to confront the fact that their daughter's beauty eclipses her own.

It is a rite of passage that most women, while far from thrilled, are pragmatic enough to accept as a part of life.

But not 50-year-old Janet. She views the small matter of being in her sixth decade as a mere technicality.

She is amused and proud that friends jokingly refer to her and her daughter as Paris and Chantelle after the platinum blonde socialite and the equally platinum former Celebrity Big Brother contestant.
